Next door neighbors Moe and Larry are using hoses from each of their houses to fill Moe's pool. They know it takes 12 hours using both hoses. They also know that Moe's hose, used alone, takes 40% less time than using Larry's hose alone. How much time is required to fill the pool using only Moe's hose?

the first thing you do is percent over a hundred and ..i don't know the rest sorry
