A) 48 km
B) 54 km
C) 60 km
D) 66 km
Correct Answer: B
Solution :
Let the distance between A and be x km, then \[\frac{x}{9}-\frac{x}{10}=\frac{36}{60}=\frac{3}{5}\]\[\Rightarrow \]\[\frac{x}{90}=\frac{3}{5}\] \[\therefore \] \[x=\frac{3}{5}\times 90=54\,\,\text{km}\]You need to login to perform this action.
