Question

64. If x people working together 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?


​

Answer 1

Answer:

k/hx

Step-by-step explanation:

man contributes his own part of the job rate so rates are additive. One man takes x times longer than x men.

x men in h hours for 1 job

1 man in h*x hours for 1 job

Having the one-man rate of 1/hx job per hour you also can say the rate is hx hours per job.

If you want the man to do work for k hours, then:

k× 1/hx= k/hx job.
