A) 14 h
B) 7 h
C) 8 h
D) 16 h
Correct Answer: C
Solution :
If a train runs at \[\frac{7}{11}\]of its normal speed, time taken \[=\frac{11}{7}\]of normal time. \[\therefore \] \[\frac{11}{7}\]of normal time = 22 \[\Rightarrow \] Normal time\[=\frac{22\times 7}{11}=14\,\,h\] \[\therefore \] Time saved \[=22-14=8\,\,h\]You need to login to perform this action.
