Question

a train 70 metres long is running at 80 kilometre per hour how much time will it take to cross platform 130 metre long?​

Answer 1

train have to cover = 70 + 130

= 200 m

By proportion

80000 m = 3600 seconds

200 m = X

X = (3600 × 200) / 80000

= 9 second

Train will take 9 sec to cover platform.
