Question

a train is moving with speed of 50 km/hr on straight track and B train is moving with speed 40 km/hr on parallel straight track in same direction .What is velocity of train A relative to train B and velocity of train B with reltaive to train A

Answer 1

Answer:

Explanation:

relative velocity of a to b =50-40=10 km/h

relative velocity of b to a =40-50=-10

Answer 2

Answer:

Relative velocity of train A to train B=Velocity of A-Velocity of B.

That is,

50-40km/h

=10km/h

Relative velocity of train B to train A=Velocity of B-Velocity of A.

That is,

40-50km/h

=-10km/h,but it is taken positive because the both trains are moving in the same direction.
