The speed of a train is 36 km/hr and it takes 10 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.Solution
Let the length of train be x m. According to the question, => 36 x (5/18) = x/10 => x = 100 m Length of the platform = 100 x (8/5) = 160 m Required time = (100 + 160)/10 = 26 seconds
