    Question

    Two cyclists start from villages R and S which are 234

    km apart. One starts from R at 6:45 a.m. at 36 km/h. Another from S at 7:45 a.m. at 54 km/h towards R. When will they meet?
    A 9:45 a.m. Correct Answer Incorrect Answer
    B 9:50 a.m. Correct Answer Incorrect Answer
    C 9:57 a.m. Correct Answer Incorrect Answer
    D 10:00 a.m. Correct Answer Incorrect Answer

    Solution

    Time gap = 1 hour β†’ Distance = 36 Γ— 1 = 36 km
    Remaining = 234 – 36 = 198 km
    Relative speed = 90 km/h
    Time = 198 / 90 = 2.2 hrs = 2h 12m
    Meeting time = 7:45 a.m. + 2h 12m = 9:57 a.m.
