The temperature at a ski resort was 12°F at 5:00 A.M. If the temperature increased by 1.5°F each hour, what would be the temperature at 12 noon?

Respuesta :

The correct answer is:

22.5° F.

Explanation:

The temperature increases 1.5° per hour.  From 5:00 AM to 12:00 PM is 12-5 = 7 hours.  This makes an increase of 1.5(7) = 10.5°.

The temperature started at 12°F; increasing by 10.5° gives us

12+10.5 = 22.5°F.
