Question

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

Answer 1

Answer:

0.05 Hours

Step-by-step explanation:

Total distance  = 270 + 130 m = 400m = 0.4km

Speed = 80 km/h

Time = Distance/Speed

Time = 0.4 / 80 = 0.05 hrs

Answer 2

Answer:

18 seconds.

Step-by-step explanation:

The total distance that has to covered to pass the platform is (270 m + 130 m) = 400 m

At speed of 80 km/hr = 80 * 5/18 = 22.22 m/sec

time = distance / speed

       = 400 / 22.22

       = 18 seconds.
