For example if the total distance travelled was 250 miles and the time it took was 5 hours then the average speed was 250 5 50 miles per hour mph. V d t where v is the velocity d is the distance and t is the time so you can read it as Speed Distance Time. Try out the free online average speed calculator for yourself and see just how easy it is to calculate average speed.
Although speed and velocity are often words used interchangeably in physics they are distinct concepts.
Average speed total distance total time Typical units are kilometers per hour kph miles per hour mph meters per second ms and feet per second fts. If a person travels from A to B at some speed say x miles per hour. Both the ways he covers the same distance but at different speeds. So if a particle covers a certain distance s in a time to then the average speed of the body is.
