The relative velocity of two objects A and B is 10 m/s. If the velocity of object A is 40 m/s then the velocity with which B is moving is (assume both objects are moving in same direction)
10 m/s
20 m/s
30 m/s
40 m/s

Solution:

Relative Velocity = V A - V B
10= 40 - V B
V B = 30 m/s

* Is 50 m/s a possible answer ?
