A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?
Then its ok.Really. If I tell you that it takes 20 seconds for a train to pass by someone standing on the side of a road you have no idea what that means?
but why it takes more time i.e. 36 seconds to cross platform then man.
i am not able to imagine and solve the question.
