Question

When Erik went to bed one winter night in northern Minnesota, the temperature was -2°F. By the time he got up the next morning, the temperature had dropped to -17°F. Assuming the temperature dropped steadily through the night, what was the temperature in the middle of the night?
-19°F
-9.5°F
-15°F
-8.5°F

Answer 1

Answer:Hi, the temperature at the middle of the night was -9.5 degrees.

Step-by-step explanation:Average of -2 degrees F and -17 degrees F is -7.5((-2+17)/2) then add in the original -2

So -9.5 is the answer.

Answer 2

Hi, the temperature at the middle of the night was 8.5 degrees.
Average of -2 degrees F and 17 degrees F is 7.5((-2+17)/2)
So 8.5 is the closest.
Hope this helps you.
