Question

    A man travels to his destination in 8 hours at his normal speed. If his speed decreases by (1/10) , he travels 40 km less in the same time. Determine his usual speed.

    A 20 km/h. Correct Answer Incorrect Answer
    B 36 km/h. Correct Answer Incorrect Answer
    C 50 km/h. Correct Answer Incorrect Answer
    D 22 km/h. Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the usual speed be 10x km/h. The reduced speed = (9/10) × 10x = 9x km/h Using the formula Distance = Speed × Time, Usual speed = 10x = 50 km/h.
