1h 15minutes, I converted each time into fractions, 2hours to
![\frac{2}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B2%7D%20)
and the 8hour to
![\frac{8}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B8%7D%20)
, this means, painter #1 finishes 1/2 of the project in 1 hour, and paither #2 finishes 1/8 of project in 1 hour, now when we make each fraction out of 2 hours, so
![\frac{2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D%20)
and
![\frac{2}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B8%7D%20)
, we add them and get
![\frac{10}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B8%7D%20)
, then as mixed number, 1 1/4 which is 1 hour and 15min<em>(1/4 of a hour)</em>
I believe im right.
