    Question

    A bus travelling at 99 km/h completes a journey in 14 hours. At what speed will it haveto cover the same distance in 18 hours?

    A.

    77 km/h

    B.

    74 km/h

    C.

    81 km/h

    D.

    69 km/h

    Correct option is A

    Given:

    Speed of the bus = 99 km/h

    Time taken for the journey = 14 hours

    Required time to cover the same distance = 18 hours

    Formula Used:

    Distance = Speed × Time

    Solution:

    Distance = 99km/h × 14hours = 1386km

    Calculate the required speed to cover 1386 km in 18 hours:

    Required Speed = 138618 \frac{1386}{18 }​ = 77 km/h

    Thus, the required speed is 77 km/h
