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
