    A bus covers a distance of 300 km in \[7\frac{1}{2}h\] and another bus covers a distance of 450 m in 9 h. The ratio of their speeds will be

    A) 2 : 3

    B) 4 : 3

    C) 4 : 5

    D) 8 : 9

    Correct Answer: C

    Solution :

    [c] \[\because \]Speed of first bus \[\text{=}\frac{\text{Distance}}{\text{Time}}\] \[\text{=}\frac{300}{15/2}=40\,km/h\] and speed of second bus             \[=\frac{450}{9}=50\,km/h\] \[\therefore \] Ratio of speeds of both buses             \[=\frac{40}{50}=4:5\]
