Question 941244: a boat which moves 36mph in still water travels 28 miles downstream in the same amount of time that it takes to travel 20 miles up stream. find the speed of the curren Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! a boat which moves 36mph in still water travels 28 miles downstream in the same amount of time that it takes to travel 20 miles up stream. find the speed of the current.
***
let c=speed of current
36+c=speed of boat downstream
36-c=speed of boat upstream
travel time=distance/speed(same for both directions)
28(36-c)=20(36+c)
1008-28c=720+20c
48c=288
c=6
speed of the current=6 mph
