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 \[=22-14=8\,\,h\]You need to login to perform this action.
