    X at 8 AM towards point Y. Another train B starts at 9 AM from point X. If they meet at 12 PM and speed of A is 33 km/hr, while that of B is 22 km/hr. Find distance between X and Y.
    A 120 km Correct Answer Incorrect Answer
    B 157 km Correct Answer Incorrect Answer
    C 145 km Correct Answer Incorrect Answer
    D 198 km Correct Answer Incorrect Answer
    E 144 km Correct Answer Incorrect Answer

    Solution

    Speed of train A = 33 kmph
    Speed of train B = 22 kmph
    Time taken by train A to meet train B at 12 PM = 4 hrs
    Time taken by train B to meet train A at 12 PM = 3 hrs
    Distance travelled by train A = 4 × 33 = 132 km
    Distance travelled by train B = 3 × 22 = 66 km
    Therefore, total distance between X and Y = 132 + 66 = 198 km
