15. A Chinese restaurant has a large goldfish pond. Suppose that an inlet pipe and a hose together can fill the pond in 5 hours. The inlet pipe alone can complete the job in one hour less time than the hose alone. Find the time that the hose can complete the job alone and
the time that the inlet pipe can complete the job alone.
hours
The time that the hose can complete the job alone is
(Round to the nearest tenth.)
hours
The time that the inlet pipe can complete the job alone is
