Question

Two trains travelling at 40 km/hr and 22 km/hr respectively in the same direction,the time taken by the faster train to pass the slower train is 1 minute.if the length of the faster train is 125 m,find the length of the slower train?

Answer 1

Ans: Relatively speed of train

therefore 18 km/hr= 5m/sec

let the length of second train= Lm

Time taken to cross each other= L+125/5

:. L+125/5= 60 = L= 175 mtr
