Question

Two trains A and B are moving on parallel
tracks with velocities 60 km/h and 90 km/h
respectively, in opposite directions. The
relative velocity of train A with respect to
train B is
(A) 30 km/h
(B) 60 km/h
(C) 90 km/h
(D) 150 km/h
​

Answer 1

Answer:

option b is the correct answer

Answer 2

Answer:

150 km/h

Explanation:

velocity of A w.r.t B = Velocity of A - Velocity of B

that is,60-(-90)

velocity of B is negative because in the opposite direction..

●so,60-(-90)=150
