With the current, you can canoe 88 miles in 4 hours. Against the same current, you can canoe only 3 4 of this distance in 6 hours. Find your rate in still water and the rate of the current.

Math, microeconomics or criminal justice
d=rt
88 = 4(b+c)= 4b+4c
(3/4)88= 66= 6(b-c)
11=b-c
44=4b-4c
88=4b+4c
44=4b-4c
add
8b= 132
b= 132/8 = 16 1/2 mph = canoe speed in still water
66=6(16.5)-6c
11= 16.5 -c
c = 5.5 mph = current speed
88 = 4(16.5+5.5) =4(22
66 = 6(16.5-5.5) = 6(11)
