Answer 1

so whats the answer

Answer 2

shorten the answer

Answer 3

To find the change in temperature during these three hours, we need to subtract the initial temperature from the final temperature.

Let's call the initial temperature at 9 a.m. T1 and the final temperature at noon T2.

T1 = -5.8 degrees Celsius
T2 = -1.6 degrees Celsius

The change in temperature during these three hours is T2 - T1.

Change in temperature = (-1.6) - (-5.8)
Change in temperature = -1.6 + 5.8
Change in temperature = 4.2 degrees Celsius

The change in the temperature during these three hours is 4.2 degrees Celsius. This means that the temperature increased by 4.2 degrees Celsius between 9 a.m. and noon.
