−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? Write and solve an equation to show your answer. Then explain what your answer means.

Answer 1

To find the change in temperature during these three hours, we need to subtract the air temperature at noon from the air temperature at 3 pm.

Temperature change = −5.8 degrees Celsius − (−1.6 degrees Celsius)

To simplify the subtraction, we can first change the signs:
Temperature change = −5.8 degrees Celsius + 1.6 degrees Celsius

Now we can add the temperatures:
Temperature change = −4.2 degrees Celsius

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

This means that the temperature dropped by 4.2 degrees Celsius from noon to 3 pm.
