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.
