The length of a train and that of a platform are equal.If with a speed of 90 kmph the train crosses the platform in one minute,then the length of the train in metres is
a)500 b)600 c)750 d)900

• 2x will be the distance travelled by the train if the length of the train= the length of the platform = x as distance= speed*time
  distance=2x
  speed in kmph=90
  speed in mps=90*5/18
  as dist=speed*time
  2x=(90*5/18)*(60sec)
  on solving x=900mts

• Speed = 90km/hr=25m/s
  T=1min=60 sec
  Let the length of train and platform be x m
  2x/60=25 (Distance/time=speed)
  x=750m
  Hence option C is correct.
