The rate of change of the relative position of an object with respect to the other  object is known as the relative velocity of that object with respect to the other.

Example:

A train A is moving on a straight track (or railway line) from  North to South with a speed of 60\frac{km}{h}. Another train B is moving from South  to North with a speed of 70\frac{km}{h}. What is the velocity of B relative to the train  A?

soln:

Considering the direction from South to North as positive, we have  velocity (vB) of train B = + 70\frac{km}{h}

and, velocity (vA) of train A = – 60\frac{km}{h}

Hence, the velocity of train B relative to train A

= v_{B}- v_{A}

= 70 – (– 60) = 130\frac{km}{h}

( pls mark it the brainliest if it was helpful.. )
