The speed of a train is 90 km/hr and it takes 15 seconds to cross a man. Find the time taken by train to cross a platform if the ratio of the length of the platform to the train length is 8:5.
Let the length of train be x m. According to the question, => 90 x (5/18) = x/15 => x = 375 m Length of the platform = 375 x (8/5) = 600 m Required time = (375 + 600)/25 = 39 seconds
