If x people working at the same rate can complete a job in h hours, what part of the same job can one person working alone complete in k hours?
If 3 friends can makeover and paint the garage in 3 hours, how long would it take just one of them to do it if the others changed their minds about doing it?
So if 3 can do it in 3 hours
1 can do 1/3 of it in 3 hours
and can do 1/3*3, or 1/9 of it in 1hour
So he can do the whole job in 9 hours.
Is that right?... CORRECT
