Question

A train passes a man in standing on platform in 13 second and also crosses the platform which is 252 m long in 31second . The train of length is ??

Answer 1

Answer:182m

Step-by-step explanation:

Let the length of train =x

Distance cover by train to cross a platform = (train length) + (platform length) i.e= (x+252)m

→Since; speed of train to cross a man = speed of train to cross a platform

x/13=x+252/31

31x/13=x+252

31x=13x+3276

18x=3276

x=182m

Hence length of train is 182m
