Answer:

9.6 hours

Step-by-step explanation:

question above can be answered through variation since time needed to paint the house is inversely proportional to the number of men working:

y = k/x

8 = k/6

k = 48

so,

y = k/x

y = 48/5

y = 9.6 hours

logic can also be applied to that question. we can say that fewer men working will result to longer time to finish the job.
