A) \[12\,\,km\]
B) \[16\,\,km\]
C) \[14\,\,km\]
D) \[8\,\,km\]
Correct Answer: A
Solution :
Speed of the boat along the current \[=9+3=12\] km/hr. and speed of the boat against the current \[=9-3=6\] km/hr. Let the distance from \[P\] to \[Q\] be \[x\]km. then \[\frac{x}{12}+\frac{x}{6}=3\] or, \[x+2x=36\] or,\[x=\frac{36}{3}=12\]kmYou need to login to perform this action.
