if it takes 4 workers 283 days to finish a project how many days will it take 9 workers to finish the same project

Question

workers work 8 hrs per day

Answer 1

You can break this down.

4 workers take 283 days. One worker would take four times as long: 1132 days.

9 workers would only a ninth of this time: 1132/9=125 7/9 days. That’s 125 days and about 6 hours.
