    D 275 km Correct Answer Incorrect Answer
    E 250 km Correct Answer Incorrect Answer

    Solution

    Let speed of train is ‘x’ m/s and length of train is ‘l’ metres According to question; l = 16x And, l + 250 = 36x Or, 16x + 250 = 36x Or, 20x = 250 Or, x = 12.5 Speed of train = 12.5 × 18/5 = 45 km/h Distance travelled by train in 5 hours = 45 × 5 = 225 km Hence, option a.
