Question

Sumith was waiting on a 200 m long railway platform when he saw a train travelling at a speed of 54 km/ hours. if the train took 50 seconds to pass the platform, what is the length of the train

Answer 1

Answer:

Platform lenth=200m

Lentof train=x

Total distance=(x+200)m

Speed=54×5/18m/s=15m/s

Time=50sec

Step-by-step explanation:

So

Time=total distance/speed

50sec=(x+200)m/15m/s

50sec×15m/s=x+200

750-200=x

550m=x
