To find the change in temperature during the three hours, we need to find the difference between the temperature at 9 AM and the temperature at noon.

Let's denote the change in temperature as ΔT.

At 9 AM, the temperature is -5.8°C.
At noon, the temperature is -1.6°C.

The equation that represents the change in temperature is:
ΔT = (-1.6) - (-5.8)
= -1.6 + 5.8

Simplifying the equation:
ΔT = 4.2

Therefore, the change in temperature during the three hours is 4.2°C.

This means that the temperature increased by 4.2 degrees Celsius from 9 AM to noon.
