    A person sees a train passing over 6 km long bridge. The

    length of the train is half that of bridge if the train clears the bridge in 3 mins. What is the speed of the train?
    A 90 km/hr Correct Answer Incorrect Answer

    C 60 km/hr Correct Answer Incorrect Answer
    D 30 km/hr Correct Answer Incorrect Answer
    E 54 km/hr Correct Answer Incorrect Answer

    Solution

    Distance covered in 6/60 hours = (6 + 6/2) = 9 km Distance covered in 1 hour = 9 x (60/6) = 90 km So, speed of the train = 90 km/hr
