Question 663851: Sally can paint a room in 5 hours while it takes Steve 8 hours to paint the same room. How long would it take them to paint the room if they worked together? Answer by vleith(2983) (Show Source):
You can put this solution on YOUR website! This is a classic type of problem. The way I do these is as follows:
Sally can paint {1/5) of the room in an hour. Steve can paint 1/8 of the room an hour.
Together they can paint room per hour room/hour
So how long to paint the whole room?
hours. About 3 hours and 5 minutes to paint the room together.
