Answer:
Therefore, total distance = 120+130=250m = 0.25km. Speed of the train = 50 km/h. Time = Distance / Speed. So, time = 0.25 /50 hours = 1/200 hours.

Answer:
According to the question, the 120m long train is covering a railway platform, measuring 130m.
==>> So, the train has to cover its own distance + Length of the Platform.
Therefore, total distance = 120+130=250m = 0.25km.
==>> Speed of the train = 50 km/h.
==>> Time = Distance / Speed.
So, time = 0.25 /50 hours = 1/200 hours.
==>> Now, 1 hour = 3600 seconds.
==>>Therefore, 1/200 hr = 3600/200 = 18 sec.
Thus, the train will take 18 seconds to cross the platform.
