Question

180m long train is running at 54 Kmph. how much time it will take to cross a platform of 120m long?

Answer 1

One minute fourty eight seconds

Answer 2

The train will cross the platform in 20 seconds.

Given data :

Length of the platform = 120 m

Length of the train = 180 m

Speed of the train = 54 km/h

So,

Total distance = (length of the platform + length of the train) = (120+180) = 300m

Now,

The train covers

54 km = 1 hour

54000 m = 60 minutes

54000 m = 3600 seconds

1 m = 3600/54000 seconds

300 m = 3600×300/ 54000 = 20 seconds (answer)
