Question 1166045: Two brothers can do a job together in 6 hours. Working alone, the younger brother takes 2 hours longer than his older brother how long does each boy take when doing the job alone? Answer by solver91311(24713) (Show Source):
The older can do the job in hours by himself, therefore he can do of the job in 1 hour. The younger brother takes two hours longer, so he can do the job in hours by himself, and therefore can do of the job in one hour. Working together, they can do the job in 6 hours, so they can do of an hour. Taking this altogether:
Solve for and then calculate .
By the way, the answers are irrational, but you are only off by about 2 and a half minutes on the 6 hour total if you round to the nearest whole number.
