Answer:

t = 20 hr

Explanation:

Given data:

Total number of machine = 10

Total time for machine is 16 hr

we know that Time \times rate = job

From the information given in the question  we have

[/tex]16\times 10x = job[/tex]

As demand in the question we have

t \times 8x = job , job will remain same as before so

solving for t

16\times 10x =  t \times 8x

t = 20 hr
