    Question

    Identify the cases where two objects moving in opposite

    directions have a relative speed of 30 km/h.
    A Object A: 40 km/h, Object B: 10 km/h Correct Answer Incorrect Answer
    B Object A: 25 km/h, Object B: 5 km/h Correct Answer Incorrect Answer
    C Object A: 20 km/h, Object B: 15 km/h Correct Answer Incorrect Answer
    D Object A: 30 km/h, Object B: 30 km/h Correct Answer Incorrect Answer

    Solution

    Explanation: When two objects move in opposite directions, their relative speed is the sum of their speeds. Here, 40 + 10 = 50 km/h, which does not match the required 30 km/h. However, the closest option is 40 km/h and 10 km/h.
