The velocity of car AvA=10 m/s 

The velocity of car B  vB=6m/s

The relative velocity is the difference between both velocities.

The formula of the relative velocity is defined as

The velocity of A relative to B is



The velocity of B relative to A is


vBA=6-10=-4 m/s

Hence, The velocity of A relative to B and vice versa is 4 m/s and -4 m/s.
