For his business, Gil has determined that the time it takes to finish a job varies inversely with the number of workers. This can be expressed as: ==\ensuremath{T=\frac{k}{w}}== where T = time, k is a constant, and w = number of workers. Gil’s records show that 18 workers can finish a job in 6 days. How many days will it take 12 workers to do the same job?

Question

A 4
B 9
C 12
D 36

Answer 1

T=KW so solve for k to use in question 6=x(18) x=1/3
So T=(1/3)(12) T=4
