You can put this solution on YOUR website! the speed of a stream is 6 mph. If a boat travels 94 miles downstream in the same time that it takes to travel 47 miles upstream, what is the speed of the boat in still water?
***
let x=speed of boat in still water.
x+6=speed of boat downstream.
x-6=speed of boat upstream.
travel time=distance/speed
..
94(x-6)=47(x+6)
94x-564=47x+282
47x=846
x=18
speed of boat in still water=18 mph
