6th Class Mathematics Related to Competitive Exam Question Bank Distance, Time and Speed

  • question_answer
    The ratio between the rates of walking of A and B is 2 : 3 and therefore A takes 10 minutes more than the time taken by B to reach the destination. If A had walked at double the speed, then in what time would he have covered that distance?

    A) 9 min.              

    B)          14 min.

    C) 15 min.             

    D)          19 min.

    Correct Answer: C

    Solution :

        Ratio of speeds =2:3 \[\Rightarrow \] Ratio of times taken = 3 : 2 Given \[3x-2x=10\Rightarrow \,x=10\] \[\Rightarrow \] A would have taken 30 minutes. But if .4 walks with double the speed, then he takes half the time, i.e., 15 minutes.
