Problema Solution
In still water, a boat averages 8 miles per hour. It takes the same amount of time to travel 12 miles downstream, with the current, as it does 6 miles upstream, against the current. What is the rate of the water's current?
The rate of the water's current is ___ mph.
Answer provided by our tutors
let speed of current be xmplh
12/8+x = 6/8-x
48 +6x ÷ 96-12x
18x = 48
x = 48/18 = 8/3mph
