The Minimum Travel Time between Coordinates calculator computest the minimum time it would take to drive between two GPS coordinates in a straight line at a specified speed..
INSTRUCTIONS: Enter the following:
- (Lat 1) Starting latitude
- (Lon 1) Stating Longitude
- (Lat 2) Ending Latitude
- (Lon 2) Ending Longitude
- (V) Max Speed
Minimum Travel Time (t): The calculator returns the minum time required to travel between the points in days, hours and minutes (dd:hh:mm), and the shortest distance in miles and feet.. These can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The Minimum Travel Time calculator uses the Haversine equation to compute the shortest distance between two points (x and y) on the Earth. It then uses a mean velocity (speed) to calculate the time necessary to travel between the two points on the globe.
The time of travel is calculated by dividing the distance traveled by the average velocity. This formula allows the user to enter two points on the globe in latitude and longitude, and a speed. This formula uses the Haversine formula to approximate the distance between the two points. The Haversine formula is based on a spherical earth model employing the Earths mean radius.
In Forensic Science, this formula can be used to determine the outer limit of time to get between points.
