Answer asap, ill give brainliest, show work steve can paint a room three times as fast as billy. when they work together, steve and billy can paint a large room in 4 hours. how many hours would it take billy to paint it by himself?

Hey there! :D

If Steve does 3 times the work, we can conclude that he did 3/4 of the job. Billy did 1/4 of the job in 4 hours. We only painted 1/4 of the room in 4 hours. 

That means it would take him 16 hours to complete one room. 4*4= 16. 

It would take him 16 hours to paint a large room by himself. 

I hope this helps!
