    Question

    Two individuals, X and Y, travel from point P to point Q

    at different speeds. X takes 10 hours to complete the journey, while Y takes 12 hours. The difference in their speeds is 8 km/h, with one traveling faster than the other. Determine the distance between points P and Q.
    A 125 km Correct Answer Incorrect Answer
    B 155 km Correct Answer Incorrect Answer
    C 192 km Correct Answer Incorrect Answer
    D 180 km Correct Answer Incorrect Answer

    Solution

    ATQ;

    Let Y's speed = 'y' km/h,

    X's speed = (y + 8) km/h

    Time ratio = Y : X = 12 : 10

    Speed ratio = 10 : 12

    Using the given speed difference,

    y = 16 km/h

    Distance = Speed × Time = 16 × 12 = 192 km
