Question 977587: An experienced house painter can paint an inside wall in under twenty minutes. An inexperienced house painter can take up to one hour. If a team of an experienced painter and an inexperienced painter work on a room together, what is the longest it should take them to paint the four walls, if they finish at the same time? Answer by solver91311(24713) (Show Source):
If the experienced guy does a wall in 20 minutes, which is a third of an hour, he can do 3 walls in an hour. The other guy does the 4th wall in the same hour.
