The velocity of a car A is to 5î. The velocity of another car B is 22î – 7ĵ. What is the relative velocity of A with respect to B?
(a) -17î + 7ĵ
(b) 7î + 17ĵ
(c) -7î + 17ĵ
(d) -17î + 7ĵ

Right choice is (a) -17î + 7ĵ
To explain I would say: The formula for calculating relative velocity of a body with respect to another body is- relative velocity = Velocity vector of A – Velocity vector of B. Hence, here, the relative velocity = velocity of B – velocity of A = -17î + 7ĵ.
