Explanation:
given = Two parallel rail tracks run north-south.
Train A moves north with a speed of 54 km/h.
train B moves south with a speed of 90 km
Hence, velocity of train B w.r.t train A is 144 km/h toward south.
Velocity of train B
= 90 km/h
Hence, velocity of ground train B is 90 km/h towards north.
= 90 - 54 = 36 km/h
Hence, velocity of Train A will be 36 km/h toward north. Ans.
