Question

Under what condition is the average velocity equal to instantaneous velocity?

Answer 1

When the velocity is constant.

Answer 2

When a body moves with uniform motion, its average velocity will be equal to instantanous velocty.

For Example , let a body is moving uniformly with velocity 50km/ h .

Then instt. velocity =  50km/ h

And Average vel.  (initial vel. +final vel. )/2 = 50km/h
