Find the rate at which you work, that is, the # of walls painted per hour:

13 1/3 walls 40/3

------------------ = ---------- wall per hour

14 1/4 hr 57/4

Keep 40/3 as it is; invert the divisor (57/4) and then multiply the result by 40/3:

40 4 160 wall

------ * ------ = --------------- = approx. 0.94 wall in one hour, or 160/171 wall / hr

3 57 171 hr
