To find the range of temperatures during the 12-hour period, we need to calculate the difference between the highest and lowest temperatures recorded during that period.

Given:

• Highest temperature: 65°F
• Lowest temperature: -26°F

The formula to find the range is:

$\text{Range} = \text{Highest Temperature} - \text{Lowest Temperature}$

Substitute the given temperatures into the formula:

$\text{Range} = 65 - (-26)$

Since subtracting a negative number is equivalent to adding the absolute value of that number:

$\text{Range} = 65 + 26 = 91$

Therefore, the range of temperatures during the 12-hour period is 91°F.
