Question

    Two trains having the same speed are running in opposite

    directions. If the length of each train is 120 metres and they cross each other in 8 seconds, then, what is the speed of each train (in km/h)?
    A 54 Correct Answer Incorrect Answer
    B 60 Correct Answer Incorrect Answer
    C 45 Correct Answer Incorrect Answer
    D 50 Correct Answer Incorrect Answer

    Solution

    Let the speed of each train be x m/sec. Relative speed of the train = 2x m/sec. So 2x = (120+120)/8 2x=240/8 X=15. Speed of each train =15×18/5 =54km/h
