Question

The amount of time t (in hours) it takes to complete a certain job varies inversely with the number of workers, w. The constant of variation is 28. Find the time it takes to complete the job when the number of workers is 16.

Answer 1

1.75 h

Explanation:

t = k/w

k = 28

t = 28/w

If w = 16,

t = 28/16

t = 1.75 h

It will take 16 workers 1.75 h to complete the job.
