Question

9°F. By the afternoon, the temperature had risen to –
2°F.
What was the change in temperature from the morning to the afternoon?

Answer 1

To calculate the change in temperature from the morning to the afternoon, we can use the following formula:

\[ \text{Change in Temperature} = \text{Afternoon Temperature} - \text{Morning Temperature} \]

In this case, the morning temperature is \(-9°F\) and the afternoon temperature is \(-2°F\). Plugging in the values, we get:

\[ \text{Change in Temperature} = -2°F - (-9°F) = -2°F + 9°F = 7°F \]

Therefore, the change in temperature from the morning to the afternoon is \(7°F\).
