    Speed of the two trains = 43 km/h and 51 km/h Since the trains are moving in opposite directions, => Relative speed = 43 + 51 = 94 km/h = $$(94 imesfrac{5}{18})$$ m/s = $$(frac{235}{9})$$ m/s Since the observation given is of a passenger sitting in faster train, distance travelled is equal to length of the slower train. Let it be = $$d$$ m
    Using, distance = speed x time => $$d=frac{235}{9} imes9=235$$ m => Ans - (A)
