Question
The speed of a Vande Bharat train is 72 km/h, and it
takes 16 seconds to cross a tree. Determine the time taken by the train to cross a platform when the ratio of the length of the platform to the length of the train is 11:8.Solution
ATQ, Let the length of Vaande Bharat train = 'l' m 72 × 5/18 = l/16 20 × 16 = l l = 320 m Length of the platform = (320/8) × 11 = 440 m Required time = (320 + 440)/20 = 760/20 = 38 seconds
