Question

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?

Answer 1

The correct answer is:

22.5°F.

Step-by-step explanation:

The temperature rises 1.5°F each hour. From 5:00 AM to 12:00 PM is 12-5 = 7 hours. This gives us a rise of 7(1.5) = 10.5°.

An increase of 10.5° makes the new temperature 12+10.5 = 22.5°F.
