Question

hi good morning
please help me​

Answer 1

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
