The time, t, required to complete a job

varies inversely with the number of people,

p, working on the job. If it takes 7.125

hours for 8 workers to complete a job, how

many hours will it take if there are 3

workers?

19 hrs

Step-by-step explanation:

t varies inversely with number of people p

t = k/p

If it takes 7.125 hrs for 8 workers to do the job

K = tp

= 7. 125 x 8

= 57

How many hours will it take if there are 3 workers.

Recall t = k/p

t = 57/3

= 19 hrs

Therefore, It'll take 19 hrs to Complete the job if there are only three workers.
