If A can do a job in x time periods, then A can do 
of the job in 1 time period. Likewise, if B can do the same job in y time periods, then B can do 
of the job in 1 time period.
So, working together, they can do
of the job in 1 time period.
Therefore, they can do the whole job in:
time periods.
So 
and 
hrs.
Or 4 hrs 7 minutes give or take a few seconds. That means that if they start at 7AM, they will be done by 11:07 and Moe takes his lunch break AFTER they are done.
