Question 1152870: Sally can paint a room in 4 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? Found 2 solutions by VFBundy, Alan3354:Answer by VFBundy(438) (Show Source):
You can put this solution on YOUR website! Sally's rate of work = 1/4 room per hour
Steve's rate of work = 1/8 room per hour
Rate working together = 1/4 + 1/8 room per hour = 3/8 room per hour
If they can paint 3/8 room per hour, that means it takes them 8/3 hours to paint the room.

A different approach:
----
Sally's work = that of 2 Steves.
--> 8/3 hours
======================
Or,
8*4/(8+4) = 32/12 = 8/3 hours
