a train is moving at a speed of 60kmph.if the lenght of the trainis 100m,then how long will it take to cross a railway platform 150m long?

• speed of train= 5/18*60= 16.66m/s
  now time taken to cross platform= 100+150/16.66= 15seconds ans...

• speed=60*(5/18)=50/3
  150+100=250
  250(50/3)=61.6*50
  ans=380

• it takes 15 sec to cross the length of platform and its own length

• length of train+length of platform=S*T
  100+150=60*T
  T=25/6*18/5=15 second

• ans is 15.
  distance=250m(100+150)
  speed=60kmph
  time=distance/speed
  time=250*(18/5)/60
  =15.
