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.
