    Question

    ‘K’ and ‘L’ are going from place ‘X’ to

    place ‘Y’, which is 1100 km apart. If ‘K’ started 3 hours after ‘L’ but both of them reached ‘Y’ at the same time, then find the speed of ‘L’. The difference between their speeds is 20 km/hr.
    A 95 km/hr Correct Answer Incorrect Answer
    B 85 km/hr Correct Answer Incorrect Answer
    C 80 km/hr Correct Answer Incorrect Answer
    D 75 km/hr Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the speed of ‘K’ be ‘b’ km/hr Therefore, speed of ‘L’ = (b – 20) km/hr According to the question, Since speed cannot be negative therefore, b = 100 Therefore, speed of ‘L’ = b - 20 = 80 km/hr
