You can put this solution on YOUR website! The speed of a stream is 6 mph. If a boat travels 88 miles downstream in the same time that it takes to travel 44 miles upstream, what is the speed of the boat in still water?
***
let x=speed of the boat in still water.
(x+6)=speed of the boat downstream.
(x-6)=speed of the boat upstream.
travel time=distance/speed (same for both upstream and downstream)
..
cross-multiply)
88(x-6)=44(x+6)
88x-528=44x+264
44x=792
x=18
speed of the boat in still water=18 mph
