  1. Train speed 90 km /h
    1st we have to change in m/s. then 90*5/18=25m/s
    Then d=speed*time
    =25*10=250m train length

  2. 250m

    S = 90km/hr T =10s
    T = 10s
    D = S*T
    D= ( 90*5/18) *10s
    D= 250m

  3. speed x time = distance
    (90/3.6)x10 = 250m

  4. Speed= 90km/hr
    Time= 10 S
    Length=?
    Length= speed× Time
    =90×(18/5)×10
    =25×10
    = 250m

  5. 250
    cos 90kmph is 90*1000/3600 so 25m/s
    if the train crosses it in 10 sec then the length is
    25*10=250 m
