A train 240 m long passes a pole in 24 seconds.How long will it take to cross pass a platform 650 m long?

• train crosses a pole with speed 240/24=10 m/s
  time taken to cross a platform is (650+240)/10= 89 sec or 1 min 29 sec

• speed of train=240/10=24m/sec
  dist to be covered by train to cross platform=length of train+ length of platform
  time req=(650+240)/10=89 sec

• Answer is 89 sec
  explanation SPEED = DISTANCE/TIME
  SPEED = 240/24 = 10sec
  
  10=(240+650) = 89 SEC

• 240 in 24 sec
  then 650 in 65

• since the train is crossing the pole in 24 sec
  hence the speed of train is = 240/24 = 10m/s
  hence the train will cross the platform in = 650/10 = 65 sec

• speed = 240/10
  sp = 24.
  time = 240+650/10
  t = 89

• speed=distance/time
  =240/24=10
  time=distance/speed
  =240+160/10=40sec
