    Question

    Two trains, each 110 meters long, are running in

    opposite directions. If the speed of one train is twice that of the other and they take 12 seconds to cross each other, find the speed of the slower train.
    A 19 km/hr Correct Answer Incorrect Answer
    B 22 km/hr Correct Answer Incorrect Answer
    C 35 km/hr Correct Answer Incorrect Answer
    D 27 km/hr Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Total distance travelled by the trains = 110 + 110 = 220 meters = 0.22 km Time taken = (12/3600) hours Let the speed of the slower train be ‘x’ km/hr Speed of the faster train = 2x km/hr Their relative speed = (2x + x) = 3x km/hr According to the question, Therefore, the speed of the slower train = 22 km/hr.
