Blake and ned work for a home remodeling business. they are putting the final touches on a home they renovated. working alone, blake can paint one room in 9 hours. ned can paint the same room in 6 hours. how long will it take them to paint the room if they work together?

Blake can do the work in 9 and part of work in 1 hour = 1/9

Ned can paint the same room in six hours, as well as do part of work in 1 hour = 1/6

If they do it together = 1/9+1/6=5/118, and they can do 5/18 part of work in hour = 1

So, they can do whole work in hours = 1/5/18=3.6

So if they do it together it will only take 3.6 hours.

40 i don’t know lololol
