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
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.

An exterior angle of a triangle is equal to the sum of the opposite interior
angles
9x = 5x + 9 + x
9x = 6x + 9
9x - 6x = 9
3x = 9
x = 9/3
x = 3
