  • question_answer
    With a uniform speed a car covers a distance in 8 hours. Had the speed been increased by 4 tan/hr, the same distance could have been covered in \[7\frac{1}{2}\] hours. The distance covered is

    A)  400 km

    B)  450 km

    C)  480 km

    D)  380 km

    Correct Answer: C

    Solution :

    [c] Let the distance be x km. According to question \[\frac{x}{7\frac{1}{2}}-\frac{x}{8}=4\] \[\Rightarrow \] \[\frac{2x}{15}-\frac{x}{8}=4\] \[\Rightarrow \] \[\frac{16x-15x}{120}=4\] \[\Rightarrow \] \[x=480\,km\]
