Seven identical editors working independently need 16 hours to check a fixed collection of records. How many hours would 8 such editors need at the same rate? Enter the number of hours.

Explication

The checking task contains 7 times 16, or 112 editor-hours, so eight editors need 112 divided by 8, which is 14 hours. Direct scaling would give about 18.29 hours and wrongly predict that a larger team needs more time.
