Aaron can paint a door in 6 h, and Ana can do the same job in 3 h. Working together, how many hours will it take them to paint a door?

Answer 1

.166t+.333t=.5t

9*.5=4.5hrs

Answer 2

Hi Dezarae

Aaron takes 6 h to paint a door or 6 * 60 min, 360 minutes per door

Ana takes 3 h to paint a door or 3 * 60 min, 180 minutes per door

Since you have two painters for one door we can calculate the average of their combined times as

(360 + 180) minutes/2

540 minutes /2 = 270 minutes

270 minutes x 1 h/60 minutes = 4.5 h

I hope this helps
