A sailboat travels 20 miles downstream in 3 hours. It returns in 4 hours. Find the speed of the sailboat in still water and rate of the current This question is from textbook Algebra Structure and Method
You can put this solution on YOUR website! make the boat =x
make the water =y
against flow 4(x-y)=20
with flow 3(x+y)=20
distance is equal so the two equations are equal
4(x-y)=3(x+y)
4x-4y=3x+3y
x=7y
-------------
substitute 7y for x in equation
4(7y-y)=20
28y-4y=20
24y=20
y=.83 mph speed of water
------------------------------------
speed of boat=7y=7(.83)=5.81 mph
