    Question

    A goods train 350 m long passes through a tunnel of

    length 1250 m in 80 seconds. What is the speed of the train?
    A 64 km/h Correct Answer Incorrect Answer
    B 56 km/h Correct Answer Incorrect Answer
    C 78 km/h Correct Answer Incorrect Answer
    D 72 km/h Correct Answer Incorrect Answer

    Solution

    ATQ, Let speed of train be x km/hr, then x × (5/18) = (350 + 1250)/20 = x = 20 × (18/5) = x = 72 km/hr. ∴ Speed of train is 72 km/hr.
