Question

The amount of workers varies inversely with the time, in days, to complete a project. Five workers can complete a certain project in 24 days. How many workers will be needed to complete the project in 15 days?

Answer 1

9514 1404 393

Answer:

  8

Step-by-step explanation:

The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.

  (5 workers) × (8/5) = 8 workers

8 workers are needed to complete the project in 15 days.
