Suppose we have two bodies A and B moving with velocities v a and v b respectively.
Then the relative velocity of A w.r.t B is given by, v a,b = v a - v b
And the relative velocity of B w.r.t A is given by, v b,a = v b – v a
Thus relative velocity of a moving body, A, with respect to another moving body, B, is found by considering B to be fixed and then finding the velocity of A which an observer resting on B will observe.
When A and B are moving the the same direction and their respective velocities are va and v b . Then, the relative velocity of A w.r.t B is given by, v a,b = v a - v b
And the relative velocity of B w.r.t A is given by, v b,a = v b – v a
When A and B are moving towards each other. The velocity of A will be v a and the velocity of B will be –v b . The negative sign appears because the direction of velocities are opposite.
So, relative velocity of A w.r.t B is, v a,b = v a – (-v b ) = v a + v b
And the relative velocity of B w.r.t. A is, v b,a = -v b - v a = -(v a + v b )
Then the relative velocity of A w.r.t B is given by, v a,b = v a - v b
And the relative velocity of B w.r.t A is given by, v b,a = v b – v a
Thus relative velocity of a moving body, A, with respect to another moving body, B, is found by considering B to be fixed and then finding the velocity of A which an observer resting on B will observe.
When A and B are moving the the same direction and their respective velocities are va and v b . Then, the relative velocity of A w.r.t B is given by, v a,b = v a - v b
And the relative velocity of B w.r.t A is given by, v b,a = v b – v a
When A and B are moving towards each other. The velocity of A will be v a and the velocity of B will be –v b . The negative sign appears because the direction of velocities are opposite.
So, relative velocity of A w.r.t B is, v a,b = v a – (-v b ) = v a + v b
And the relative velocity of B w.r.t. A is, v b,a = -v b - v a = -(v a + v b )

Here is anS ...
the vector difference between the velocities of two bodies : the velocity of a body with respect to another regarded as being at rest is called relative velocity
Derivation ...
Relative velocity is used to describe the motion of airplanes in the wind or moving boats through water etc. This velocity is computed according to the observer inside the object. This can be computed by introducing an intermediate frame of references. In simpler words, this can be the vector some of the velocities. Formula for relative velocity is articulated as,
V vector =VAB vector + VBC vector
Where,
VAB is the velocity with respect to A and B, VBC is the velocity with respect to B and C and VACVAC is the velocity with respect to A and C.
