    A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

    ক)
    230 m
    খ)
    240 m
    গ)
    260 m
    ঘ)
    270 m

    Explanation

    Speed = (72 x (5/18)) m/sec. = 20 m/sec. Time = 26 sec. Let the length of the train be x metres. Then, (x + 250)/26 = 20 => x + 250 = 520 So, x = 270.
