Q:

Choose the most appropriate answer:A boat travels upstream from B to A and downstream from A to B in 3 hours. If the speed of the boat in still water is 9 Km/h and the speed of the current is 3 Km/h, the distance between A and B is

A) 9 km B) 10 km
C) 11 km D) 12 km
 
Answer & Explanation Answer: D) 12 km

Explanation:

Speed of boat in still water = 9 km/hr

Speed of current = 3km/hr

Downstream speed = 9+3 = 12 km/hr

Upstream speed = 9-3 =6 km/hr

Let the distance between A to B be x km.

x/6 + x/12 = 3x + 2x = 36
3x = 36
x = 12 km
