  • question_answer
    Walking 6/7th of his usual speed, a man is 12 min too late. The usual time taken by him to cover that distance is

    A) 1h

    B) 1 h 12 min

    C) 1 h 15 min

    D) 1 h 20 min

    Correct Answer: B

    Solution :

    [b] We know, Time and speed are inversely proportional. \[\therefore \] Usual time \[\times \frac{7}{6}-\] usual time \[=12\min \] \[\Rightarrow \]            \[\text{Usual time }\!\!\times\!\!\text{ }\frac{\text{1}}{\text{6}}\text{=12}\,\text{min}\] \[\therefore \] Usual time \[=72\min =1\,\text{h}\,12\min \]
