One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.
How far is 1 degree of longitude at the equator?
A geographical mile is defined to be the length of one minute of arc along the equator (one equatorial minute of longitude) therefore a degree of longitude along the equator is exactly 60 geographical miles or 111.3 kilometers, as there are 60 minutes in a degree.
How many miles are between longitude lines?
The distance between longitudes at the equator is the same as latitude, roughly 69 miles. At 45 degrees north or south, the distance between is about 49 miles (79 km). What is this? The distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.
How many degrees are in a mile of latitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart. The range varies (due to the earth’s slightly ellipsoid shape) from 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles. This is convenient because each minute (1/60th of a degree) is approximately one [nautical] mile.
How many miles is 360 degrees?
The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles. That is the approximate distance between each degree of latitude.
How long does it take to pass 1 longitude?
Answer: 4 minutes take time does one longitude take to pass by the sun.
How long does it take Earth to pass one longitude?
How long does it take Earth to cross 1 longitude? The longitude degrees are rotating with the Earth. It does not switch from degree to another. It takes the Earth four minutes (1440 minutes per day/360° in a circle) to rotate one degree.
How many longitudes are there in total?
To measure longitude east or west of the Prime Meridian, there are 180 vertical longitude lines east of the Prime Meridian and 180 vertical longitude lines west of the Prime Meridian, so longitude locations are given as __ degrees east or __ degrees west.
What is the longest line of longitude?
Answer: The longest is the equator, whose latitude is zero, while at the poles, at latitudes 90° north and 90° south (or –90°), the circles shrink to a point. Both longitudes or meridians, interconnecting the north pole and the south pole, are equivalent lines of similar length.

How latitude and longitude is calculated?
One of the most common ways to calculate distances using latitude and longitude is the haversine formula, which is used to measure distances on a sphere. This method uses spherical triangles and measures the sides and angles of each to calculate the distance between points.
What is the difference between latitude and longitude?
Both longitude and latitude are angles measured with the center of the earth as an origin. A longitude is an angle from the prime merdian, measured to the east (longitudes to the west are negative). Latitudes measure an angle up from the equator (latitudes to the south are negative).
How many miles is 0.1 degrees?
How many miles is 0.1 degrees? Approximate Metric Equivalents for Degrees. At the equator for longitude and for latitude anywhere, the following approximations are valid: 1 = 111 km (or 60 nautical miles) 0.1 = 11.1 km.
How many miles is 30 degrees?
That is a total of 30 degrees. Take the amount of degrees and multiply it by 69.2 miles, which we found in Step 1. For our example of 30 miles, you have a distance of 2,076 miles.
How many degrees is 69 miles?
24,901 divided 360 equals 69 miles per degree.
How many miles is 2 degrees latitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart.
Is the latitude?
Latitude measures the distance north or south of the equator. Lines of latitude, also called parallels, are imaginary lines that divide the Earth. They run east to west, but measure your distance north or south. The equator is the most well known parallel.
Why is IDL called a calendar line?
The International Date Line is the boundary where each calendar day starts and is also known as the “Line of Demarcation” because it separates two calendar dates: When you cross the date line traveling east, you subtract a day, and if you cross the line traveling west, you add a day.
How do longitudes help us in calculating time?
Explanation: ANS Every gain or loss of 1° longitude stands for 4 minutes. … on every longitudinal degree increase towards west, substract 4 min. After the hours is calculated add(if east) or substract( if west) it with time of GMT.
How long does the Sun take to cross over 15 longitudes?
24 hours time will be taken by the sun for pass through the full 360 degrees around the world. So an equal hour of time to 15 degrees of longitude and rest can be found with the fractions of the same.
How much time will it take you to travel from a location on one longitude to the immediate next one?
The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on.

How many degrees does the Earth turn in 60 minutes?
It’s just a way of measuring very small angles. So in 1 day, the Earth turns by 360 degrees * 60 minutes per degree = 21600 angular minutes.
Are there 360 or 361 longitudes?
Longitude lines runs from North to south pole means a complete circles and hence covers 360 degrees and that is why there are 360 longitudes.
How many longitudes pass the sun in one hour?
eastern and western hemispheres. In other words, the sun traverses 150 of longitudes per hour or one degree of longitude in every four minutes of time.
How many longitudes face the sun in one hour?
Answers: 360 degrees ÷ 24 hours = 15 degrees per hour. Each time zone covers 15 degrees of longitude.
What are the 2 main lines of longitude?
1. Prime Meridian = Longitude 0o (Greenwich Meridian). 2. International Date Line (Longitude 180o).
What is the farthest possible distance from 0 longitude?
The distance around the Earth measures 360 degrees. The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line.
What is the shortest latitude?
Answer: Arctic Circle (66°33′48.3″ N) Tropic of Cancer (23°26′11.7″ N) Equator (0° latitude) is the shortest latitude. Explanation: hope this helps you.
How do you convert latitude and longitude to distance?
For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.
How do you find lat long from distance and bearing?
- latitude of second point = la2 = asin(sin la1 * cos Ad + cos la1 * sin Ad * cos θ), and.
- longitude of second point = lo2 = lo1 + atan2(sin θ * sin Ad * cos la1 , cos Ad – sin la1 * sin la2)
What do longitude lines run?
Lines of longitude, also called meridians, are imaginary lines that divide the Earth. They run north to south from pole to pole, but they measure the distance east or west. The prime meridian, which runs through Greenwich, England, has a longitude of 0 degrees.
Does latitude go first?
Handy tip: when giving a co-ordinate, latitude (north or south) always precedes longitude (east or west). Latitude and longitude are divided in degrees (°), minutes (‘) and seconds (“). There are 60 minutes in a degree and 60 seconds in a minute (similar to measuring time).
What is another name for longitude?
•longitude (noun)
meridian.
What is the maximum latitude?
The valid range of latitude in degrees is -90 and +90 for the southern and northern hemisphere, respectively. Longitude is in the range -180 and +180 specifying coordinates west and east of the Prime Meridian, respectively.
How many meters is a degree of longitude?
9 Answers. If your displacements aren’t too great (less than a few kilometers) and you’re not right at the poles, use the quick and dirty estimate that 111,111 meters (111.111 km) in the y direction is 1 degree (of latitude) and 111,111 * cos(latitude) meters in the x direction is 1 degree (of longitude).
What is the length of a degree of longitude at 22 degrees latitude?
“What is the length of a degree of longitude at 22 latitude?” About 55 nautical miles, or 63 statute miles.
How do you convert degrees to feet?
For the conversion you ask for, decimal degrees = feet / 364,567.2. Derivation: a nautical mile (nm) is 1 minute of arc along a great circle*, or 1/60th of a degree. There are 6076.12 feet per nautical mile. So, 6076.12 x 60 = 364,567.2 feet per degree.
