Question

A man was waiting on a 200m long Rail way platform when he saw a train travelling at a speed of 54km/h. If the Train took 50 seconds to pass the platform, what is the the Train ( in m)

Answer 1

Answer:

15 miles

Step-by-step explanation:

Speed of the train in m/s = \frac{54\time1000}{3600}=15\:m/.

Answer 2

Answer:

The length of the train is 550 m

Step-by-step explanation:

Length of the platform = 200m

Speed of the train = 54kmph = 15mps

Time taken to cross the platform = 50s

Therefore, total distance covered by the train before, entering the platform = 200+x metes.

We know that v = s by t,

Therefore, s = vt

200+x = 750

x = 750-200 = 550 metres
