To find the change in temperature, you need to subtract the initial temperature from the final temperature.
The change in temperature is -1.6 degrees Celsius minus (-5.8) degrees Celsius, which is equal to -1.6 + 5.8 = 4.2 degrees Celsius.
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
The air temperature at 9 am is -5.8 degrees Celsius. The air temperature at noon is -1.6 degrees Celsius. What is the change in the temperature during these three hours?
