The amount of time to complete a job varies inversely with the number of workers. Forty-two workers can finish a job in 18 days. How many days would it take 54 workers to complete the same job?

Question

A) 8 days

B) 14 days

C) 23 days

D) 126 days

Answer 1

Time T = k/W where k = the proportionality constant and W = number of workers

Find k k = TW = 42(18) = 756

So,

T = 756/54 = 14 days

So the answer if B
