Question

A train of length 200m travelling at 30m/sec overtakes another train of length 300m travelling at 20m/sec.Then the time taken by the first train to pass the second train is?

Answer 1

Hi..

First train has to cover a distance of (200 +300) m to fully overtake

Net speed = 30-20 = 10m / second

Time taken = Distance / net speed = 500/10 = 50 seconds ..

Hope this helps u!!
