A jogger runs by a river with a velocity of 7 m s relative to the ground. A leaf floating on the river moves with a velocity of 2 m s relative to the ground (riverbed). What is the velocity of the leaf relative to the jogger?

The velocity of the leaf relative to the jogger is 5 m/s.                    

Explanation:

Given that,

Velocity of jogger wrt to the ground,

velocity of leaf wrt the ground,

We need to find the velocity of the leaf relative to the jogger. Let it is equal to V. So, it is given by :

So, the velocity of the leaf relative to the jogger is 5 m/s. Hence, this is the required solution.
