A boat makes a 120-mile trip downstream. A3b - c 120 MABOO11Points 655. If b the rate of the boat in still water and c the rate of the current which of the following equations represents the trip upstream. A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours.
Asked By Wiki User. A3b - c 120 MABOO11Points 655. Let the rate at which the current flows be c and that of the boat in still water be b.
Let v be the speed of the boat in still water and c be the speed of the current. Divide both sides by 3. Boat speed - current 30mph The reason Im adding the current is because downstream the boat.

3b - c 120 4b - c 120 4b c 120 Weegy. A write 2 equations one for upstream part of the trip and one for the downstream part relating. A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours.
What is the rate of the current. The upstream speed of the boat is v-c and the downstream boat is v c. Thus c b 3 hrs 120 mi or c b 40 mihr.
