Question 30366: I'm having a difficult time setting this one up even know its a DxR=T!
A coast guard boat that patrols a river separating two counties cruises at 20 knots in still water. The river flows at 4 knots. For each patrol the captain of the boat is ordered to travel upstream and then return. His trip takes exactly 6 hours. How far upstream does the boat travel?
Thank God for you all!

Let the distance be x
Equation:

Multiply the whole equation by 96 and then simplfy
6x+4x=576
10x=576
x=57.6

Hence, the distance is 57.6
