Correct option : C:2/v=(1/v1+1/v2)
*****************************************
Explanation:
During first phase, time taken=x/v1
during second phase time taken=x/v2
Total distance=2x
Total time taken= x/v1+x/v2
=x[1/v1+1/v2]
Average velocity=2x/x[1/v1+1/v2]v=2/1/v1+1/v22/v=1/v1+1/v2

Explanation:
Avarage velocity = total displacement or distance / total time
v= d/t v= d/t
t = vx t = v2 x
Avarage speed = v + v2/vx + v2x
