Answer:
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

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.
