Both the ways he covers the same distance but at different speeds. The formula looks like this. 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.
Using the average speed formula total distance and elapsed time the average speed for the entire trip can be calculated as Note that the average speed is not 50 65 2 575 mph.
Therefore 2x 30 x15. The Average Speed of an object is a measure of the distance covered by that object in a set period of time. Therefore 2x 30 x15. He comes back from B to A at different speed say y miles per hour.
