Question 923097: I can't figure out or remember how to solve this problem:
An experienced bricklayer can construct a small wall in 3 hours. If him and his apprentice can complete the job together in 2 hours, how long does it take his apprentice to build the same wall by himself?
Please and thank you!

Their combined rate is sum of their individual rates. The rates should be used in the form of "SMALL WALLS per HOUR", or "SMALL WALL per HOURS".
