You can put this solution on YOUR website! Each man contributes his own part of the job rate so rates are additive. One man takes x times longer than x men.
x men__________________h hours for 1 job
1 man__________________h*x hours for 1 job
-----------
Having the one-man rate of job per hour you also can say the rate is hours per job.
If you want the man to do work for k hours, then: job.
