    Answer:

    time taken will be 18 sec

    Step-by-step explanation:

    Speed of the train = 80 km/hr = 80 x 1000/3600 80 x 5/18 = 200/9 m/sec

    Distance = length of the train + length of the platform = 130 m + 270 m

                    =400m

    Time = Distance / Speed

    = 400×9 / 200

    = 2 x 9

    = 18 sec.

    18sec

    Step-by-step explanation:

    Speed of the train = 80 km/hr = 80 x 1000/3600 80 x 5/18 = 200/9 m/sec

    Distance = length of the trian + length of the platform = 130 m + 270 m = 400 m

    Time = Distance / Speed

    = 400×9 / 200

    = 2 x 9

    = 18 sec.
