Finding Longitude Because one day is 24 hours long one can easily use time to calculate longitude. One hour of time difference corresponds to 15° of longitude (360°/24 hours = 15°/hour).

The similarity between longitudes and latitudes is that they are measured in the same way: in degrees, minutes, and seconds, where one degree has 60 minutes and one minute has 60 seconds.

Normal distance calculation can be done using getDistance() function which calculates the distance between two geo coordinates. This function takes up to 3 arguments. The first 2 arguments are mandatory. Coordinates can be in sexagesimal(“51° 31′ N”) or decimal(51.5103) format.

You must start by finding the difference in longitude (or degrees) of the two places. You do this by adding the two numbers. Then, divide by the 15 degrees that occurs in one hour and this will give you the time difference between two locations through the International Date Line.

Because one day is 24 hours long one can easily use time to calculate longitude. One hour of time difference corresponds to 15° of longitude (360°/24 hours = 15°/hour). Suppose an observer sets his accurate watch to 12:00 at noon in Greenwich, England and then travels a great distance.

15 degrees of longitude = 1 hour difference; 1 degree longitude = 4 minutes difference.

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.

Degrees of latitude are always 60 nautical miles apart. At the equator, a grid of 1° of longitude by 1° of latitude covers about 3,600 square miles.

Take the coordinates of two points you want to find the distance between. Call one point Point 1 (x1,y1) and make the other Point 2 (x2,y2). It does not terribly matter which point is which, as long as you keep the labels (1 and 2) consistent throughout the problem.
