Question

The farmer has a farmland that is paid $20.00 an hour to work on the farm. His job usually consists of tending to the cows and fixing broken fences, but now the farmer needs him to replace the roof on the barn. The farmer has already purchased all the materials. The only thing left to do is put it on. The farmhand can complete the job in 18 hours if he works by himself. If the farmer puts the roof on by himself it would only take him 15 hours to complete the job. How long would it take to finish the roof if the farmer and farmhand work on the roof at the same time?
