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

• Speed s = 60kmph
  => 60*5/18 m/s
  s= 50/3
  Length of the train = 100m
  t = d/s
  Reqd. time = (100+150)/50/3
  t=15 secs
  
  Ans : 15 secs

• time will start when train touches the start of the bridge.
  time interval will be upto crossing of the last compartment of the bridge.
  hence total distance travelled=(100+150)=250m
  time =d/c
  T=250/(60*5/18)
  T=15 sec answer.....

• speed=50/3 m/ses
  total distance =250 m
  time=250/(50/3)=15 sec

• Assuming the time starts when start of the train touches one end platform and stops when other end of it crosses other end of platform train will have to travel 250m to do so.
  Speed of train = 60kmph = 25mps
  therefore it will take 10 sec

• total length to cover = 100+150 m,
  speed of train in m/s = 60*5/18=50/3
  time take to cover = 250*3/50=15s

• total length=150+100=250m
  speed=60kmph=60*(5/18)mps
  16.67mps
  
  time=250/16.67
  15 sec

• speed=distance/time
  here distance to be covered to cross the flat form is train length+flatform length
  i.e.250
  time =250*18/(60*5)=15
