    Answer:

    250 m

    Step-by-step explanation:

    90 km per hour is 25 metre per second.

    1km =1000 m

    and 1 hour =60min = 3600 seconds.

    So to convert 90km/h into m/second…

    90*(1000/3600)= 25 m/s (approx)

    So if the train takes 10 seconds to cross a pole while running at 90 km/h then the length of the train is 25 * 10 which is 250 m.
