Tim can paint a room in 6 hours. Ben can paint the same room in 4 hours. How many hours would it take Tim and Ben to paint the room while working together?

Answer:2.4Step-by-step explanation:In one hour, Tim paints 1/6 and 1/4 for Ben. for the total hours they painted together 1/6x+1/4x because x=hrs and 1/6x + 1/4x = 100% is how many hrs they did in all. 100%=11/6x+1/4x=14/24x+6/24x=110/24x=15/12x=1multiply y 12/5 both sides 5/12 canceled and u get 12/5 or 2.4 hrs.
