Question

Garib Rath Express of length 360 meters crosses a pole in 9 seconds. In what time it will cross the Hyderabad platform of length 200 meters?

  • 7
  • 14
  • 21
  • 28
Answer- B

Time taken to cross the platform = total distance/speed

Distance covered = length of train + length of platform

= 360 + 200 = 560 meters

Speed of train = Distance (length of train) / time taken to cross the pole = 360/9 = 40 m/s

So,time taken to cross the platform = 560/40 s = 14 seconds.
