Question

How long will a train, 120 m long, take to clear a platform, 130 m long, if its
speed is 50 km/hr?​

Answer 1

Step-by-step explanation:

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.
