  2.  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

    (C).89 seconnfd

  3. 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

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