Problema Solution
Suppose that the time it takes to do a job is inversely proportional to the number of workers. That is, the more workers on the job the less time required to complete the job. If it takes 3 workers 16 days to finish a job, how long will it take 8 workers?

let 'x' represent the number of days that 8 workers need to finish the job
3*16 = 8*x
by solving we find:
x = 6 days
