Question

A man moves from a place P to Q with speed 40m/s then he returns back to P along the same route speed 20m/s. calculate the average speed and average velocity ​

Answer 1

Answer:

Average velocity is equal to zero because displacement is zero as the initial and final positions of the man are same.

Average speed=(2×40×20)/20+40

=80/3

=26.6m/s
