  1. Freight train DATA:

    rate = x-14 kmh; distance = 330 km ;time = d/r = 330/(x-14) hrs

    Passenger Train DATA:

    rate = x km/h ; distance 400 km ; time = d/r = 400/x hrs

    Equation:

    time = time

    330/(x-14) = 400/x

    330x = 400x - 14*400

    70x = 14*400

    x = 80 km/h (speed of the passenger train)

    ---

    x-14 = 66 km/h (speed of the freight train)
