A) 6 km
B) 5 km
C) 11 km
D) 16 km
Correct Answer: A
Solution :
Let the distance be d km. Time taken to travel at \[6\,kmph\,=\frac{d}{6}h\] Time taken to travel at \[4\,kmph\,=\frac{d}{4}h\]. Given that, \[\frac{d}{4}-\frac{d}{6}=\frac{30}{60}\] \[\Rightarrow \,\,d=6\,km\]You need to login to perform this action.
