Jesse is traveling up and down a stream in a kayak. He can paddle the kayak at n average rate of 5 mile/hour, and the round-trip is a total distance of 16 miles.When c is the speed of the current,this expression can be used to find the difference of the time it takes Jesse to travel upstream (against the current) and downstream (with the current). \(\frac { 8} { 5- x} - \frac { 8} { 5+ x} \)

Answer

\(\frac { 40+ 8c- 40+ 8c} { 25- c^ { 2} } \)=\(\frac { 16c} { 25- c^ { 2} } \)
