Question

a train pass a platform 110m long in 40sec and a boy standing on a platform in 30sec. find the length of the train?​

Answer 1

Answer:

330 m

Step-by-step explanation:

Let the length of train be x metres

(x + 110)/40 = s

Also,

x/30 = s

So, (30s + 110) = 40s

10s = 110

s = 11 m/s

x = 30s = 30*11 = 330 m
