    Question

    Two trains start from points A and B, 300 km apart, and

    travel towards each other. Train 1 starts from A at 60 km/h, while Train 2 starts from B at 40 km/h. Train 1 stops for 30 minutes after every 2 hours of travel. After how much time will they meet?
    A 3 hours Correct Answer Incorrect Answer
    B 4 hours Correct Answer Incorrect Answer
    C 5 hours Correct Answer Incorrect Answer
    D 6 hours Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Relative speed of trains = 60 + 40 = 100 km/h. Without halts, time to meet = 300 ÷ 100 = 3 hours. Train 1 travels for 2 hours before taking a 30-minute break. After 3 hours, Train 1 has taken 1  break, adding 0.5 hours. Total time = 3 + 0.5 = 3.5 hours. Correct option: e
