1. The problem statement, all variables and given/known data Dear Mentors and PF helpers, Please help me with this question as my junior asked me but I have some doubts in it: It takes 4 workers to complete repairing the road in 42 days. Suppose that 14 days into the road works, 10 more workers are brought in to help out in the road works. Calculate the total number of days needed to complete the road works in this case. 2. Relevant equations y = k/x , where k is a constant and y and x are variables 3. The attempt at a solution let y be days and x be number of workers 42 = k / 4 168 = k From the question they trying to ask if during the 14 days of work with 14 men but after this 14 days it's going to be 4 men working again. Suppose there are 14 workers ("10 more workers are brought in to help..."): d = 168 / 14 = 12 It takes 12 days to complete the repairing, but why the question says " Suppose that 14 days into the road works ..." Can anyone help me? Thank you for your time.
