    Question

    Two trains of same length are running in parallel tracks

    in the same direction with speed 50 km/hr and 120 km/hr respectively. The latter completely crosses the former in 54 seconds. Find the length of each train (in m).
    A 515 m Correct Answer Incorrect Answer
    B 540 m Correct Answer Incorrect Answer
    C 525 m Correct Answer Incorrect Answer
    D 500 m Correct Answer Incorrect Answer

    Solution

    When two trains cross each other, they cover distance equal to the sum of their lengths with relative speed. ┬аLet's take length of each train = x So, total length of both trains = 2x Relative speed = (120 тАУ 50) ├Ч (5/18) = 175/9 m/sec. тИ┤ Total length = Time ├Ч Relative speed тЗТ ┬а2x = (54 ├Ч 175)/9 тЗТ ┬аx = 525 m
