Explanation:
a) average speed =total distance /total time
average speed=250+250/5+5
=500/10
=50km per hour
b)average velocity=total displacement/total time
As we know,displacement is final position-initial position. Displacement is 0 in this case as the bus comes back to its position.
Therefore, average velocity=0/10=0km per hour
