    1. 240/24=650/x
      650/x=10
      x=650/10
      x=65

    2. speed (S) = D/t
      = 240m/24s
      = 10m/s

      t = D/S
      = 650+240/10
      =890/10
      =89 seconds

    3. for 240 m —– 24 sec
      for 240+650 m—— ?

      Cross multiple 890*24 / 240+89 sec

    5.  240 m long train, the time it takes to cross a pole is 24 seconds,to find the time that the same train will take to cross a 650 m platform. Hence, we got the speed of the train as 10 m/s. From the top calculations, the train will take 89 seconds to cross the platform so the answer is

    10. 240=24
      650=X
      240X=650X24
      X=15600/240
      X=65

    11. Actual speed of train 240m/24 sec i.e. 10m/sec..
      Now time taken by train to cross a platform of 650 m will be
      Total distance/speed
      I.e. (650+240)m/10m/sec…
      890m/10m/sec
      89sec

    12. s=D/t
      Train’s speed=240/24=10m/s
      distance=(240+650)=890m
      time=D/s
      time=890/10
      time=89
