The first hose can fill the pool in 3 days, so it can fill 1%2F3 of the pool in one day. The second hose can fill 1%2F2 of the pool in one day.

Together they can fill 1%2F3%2B1%2F2=2%2F6%2B3%2F6=5%2F6 of the pool in one day, so they can fill the pool in 6%2F5 of a day. Presuming a day is 24 hours, because garden hoses don't ordinarily have to eat, sleep, or use the restroom, then 6%2F5%2A24=28.8hours. But .8 hour is .8%2A60=48 minutes, so the total time is 1 day, 4 hours, and 48 minutes.
