The air temperature at 9 a.m. 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?

Answer 1

The change in temperature between 9 a.m. and noon is calculated by subtracting the initial temperature from the final temperature:

-1.6°C - (-5.8°C) = -1.6°C + 5.8°C = 4.2°C

Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
