Question
The speed of a train is 72 km/hr and it takes 12 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 11:6.Solution
Let the length of train be x m. According to the question, => 72 x (5/18) = x/12 => x = 240 m Length of the platform = 240 x (11/6) = 440 m Required time = (240 + 440)/20 = 34 seconds
