  1. 0.8 pages per minuteBonne réponse
  2. 1.25 minutes per pageBonne réponse
  3. 48 pages per hourBonne réponse
  4. 72 seconds per page

Explication

The printer makes 32 divided by 40, or 0.8, pages per minute, whose reciprocal is 1.25 minutes per page; over 60 minutes it makes 48 pages. A claim of 72 seconds per page is close but false because 1.25 minutes equals 75 seconds.
