Question

Two cars A and B are moving along a straight road in the same
direction with velocities of 25 km/h and 30 km/h, respectively.
Find the velocity of car B relative to car A.

Answer 1

Answer:

This is related to relative motion,

Let the two cars moving in the same direction be A and B and the third car be C.

Let the velocity of C be 'u'.

So the velocity of C with respect to B would be. u+30(as they are moving in opposite directions).

Do the speed u+30 would be given by:

=u+30⇒75=u+30

Hence u=45kmph
