Try This!

Here are two additional problems to try:

a) Two painters were hired to paint a building. The first painter could do it himself in 7 hours and the second painter could do the job himself in 5 hours. If the two painters work together, how long will it take the two painters to do the job.

***The hint for this problem is that the first painter can paint \(\Large \frac{1}{7}\) of the building in an hour. ***

b) It takes two builders six months to build a house. One builder works 1.5 times faster than the other builder. How long would it take the slower builder to build the house by himself?
