    Question

    100 metre long train β€˜A’ can cross a platform of

    length 50 metres in 20 seconds. If the speed of train β€˜B’ is 6 m/s more than that of train β€˜A’, then find the distance travelled by train β€˜B’ in 5 hours.
    A 213 km Correct Answer Incorrect Answer
    B 223 km Correct Answer Incorrect Answer
    C 203 km Correct Answer Incorrect Answer
    D 243 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Speed of train β€˜A’ = {(100 + 50)/20} = (150/20) = 7.5 m/s Speed of train β€˜B’ = 7.5 + 6 = 13.5 m/s = 13.5 Γ— (18/5) = 48.6 km/hr Required distance travelled by train β€˜B’ = 48.6 Γ— 5 = 243 km
