To find the change in temperature from 9 am to noon, we can use the following equation:
\[ \text{Change in Temperature} = \text{Temperature at Noon} - \text{Temperature at 9 am} \]
Substituting the given values:
\[ \text{Change in Temperature} = -1.6 , \text{degrees Celsius} - (-5.8 , \text{degrees Celsius}) \]
This can be simplified as:
\[ \text{Change in Temperature} = -1.6 + 5.8 \]
Now calculate:
\[ -1.6 + 5.8 = 4.2 , \text{degrees Celsius} \]
So, the change in temperature is \( 4.2 , \text{degrees Celsius} \).
Explanation:
The result of \( 4.2 , \text{degrees Celsius} \) indicates that the air temperature increased by \( 4.2 \) degrees Celsius between 9 am and noon. This means that from a chilly morning of \( -5.8 \) degrees Celsius, the temperature rose to \( -1.6 \) degrees Celsius, marking a notable warm-up over the three-hour period.
