    A train running at \[\frac{7}{11}\]of its own speed reached a place in 22 h. How much time could be saved if the train would run at its own speed?

    A)  14 h                            

    B)  7 h     

    C)  8 h      

    D)  16 h

    Correct Answer: C

    Solution :

    Since, the train runs at \[\frac{7}{11}\]th of its own speed, the it takes is \[\frac{7}{11}\]th of its usual speed. Let the usual time taken be t h. Then we can write, \[\frac{11}{7}t=22\] \[\therefore \]                  \[t=\frac{22\times 7}{11}=14\,\,h\] \[\therefore \]Time saved \[=22-14=8\,\,h\]
