    Explanation:

    Let length of both train and platform be x.

    Distance covered by the train to cross the platform = x + x = 2x

    Time = 1 min = 60 s

    and speed = 90 km/h

    = 90×518=25m/s

    Therefore, Distane = Speed×Time

    = 2x = 25 x 60

    = x = 750 m

    Let length of both train and platform be x.

    Distance covered by the train to cross the platform = x + x = 2x

    Time = 1 min = 60 s

    and speed = 90 km/h

    = 90×518=25m/s

    Therefore, Distane = Speed×Time

    = 2x = 25 x 60

    = x = 750 m
