A train 150m long passes a telegraph post in 12s.Find speed of the train.

A train is running at the rate of 40km/h. A man is also going in the same direction parallel to the train at a speed of 25km/hr. If the train crosses the man in 48s find length of the train.

How many seconds will a train 60m in length, travelling at the rate of 42km/hr take to pass another train 84m long, proceeding in the same direction at the rate of 30km/hr.

Length of two trains running in opposite directions are 170m and 190m repectively.If Speed of the first is 30km/hr and the second is 24km/hr,find in how many seconds will they meet?

Two trains are moving in the same direction at 50km/hr and 30km/hr.The faster train  crosses a man in the slower train in 18s.Find length of the faster train.

A train takes 5s to pass an electric pole.If the length of the train is 120m,find the time taken by it to cross a railway platform 180m.
