Solve the following word problem the air temperature at 9 AM is -5.8°C. The air temperature at noon is -1.6°C. What is the change in temperature during these three hours right in Solvang equation to show your answer, then explain what your answer means.

To find the change in temperature between 9 AM and noon, we can use the following equation:

\[
\text{Change in Temperature} = \text{Temperature at Noon} - \text{Temperature at 9 AM}
\]

Given:
- Temperature at 9 AM = \(-5.8°C\)
- Temperature at Noon = \(-1.6°C\)

Now, substituting these values into the equation:

\[
\text{Change in Temperature} = (-1.6°C) - (-5.8°C)
\]

This simplifies to:

\[
\text{Change in Temperature} = -1.6°C + 5.8°C = 4.2°C
\]

### Explanation:

The change in temperature from 9 AM to noon is \(4.2°C\). This means that the temperature increased by \(4.2°C\) over the three-hour period. Initially, the air temperature was \( -5.8°C\) and by noon, it had risen to \( -1.6°C\). Therefore, it signifies a warming trend in the air temperature during this time frame.
