Question

    A person covers a distance of 360 km in 4 hours. If the

    person's speed decreases by 16 (2/3)% and the distance to be covered increases by 25%, how long will it take to cover this new distance?
    A 8 hours Correct Answer Incorrect Answer
    B 6 hours Correct Answer Incorrect Answer
    C 9 hours Correct Answer Incorrect Answer
    D 10 hours Correct Answer Incorrect Answer

    Solution

    Initial speed = (360/4) = 90 km/h New speed = (5/6) x 90 = 75 km/h (because 16 (2/3)% = 1/6 ) New distance = 1.25 x 360 = 450 kms New time = (450/75) = 6 hours
