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.
Relative speed=42-30=12km/hr=12*(5/18)
Length=60+84=144m
Time=144*18/12*5=(12*18)/5=216/5=43.2s
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.
How long does a train 110m long running at the rate of 36km/hr take to cross a bridge 132m in length?
