Question

A train 270 m long is running at 80km/hr . How much time will it take to cross a platform 130 m long?

Answer 1

Answer:

18 sec

Step-by-step explanation:

Length of the train is 270 m (given)

it runs 80 km/hr. (given)

if it crosses a platform it have to cross the length of the train and the length of the platform.

so,

in 3600 sec. the cross (80×1000)m

= 80000 m

1m it crosses (3600/80000)sec.

270+130 = 400 m it crosses (3600/80000)×400 sec.

= 18 sec.
