Question

Solve the following word problem. The air temperature at 9 AM is -5.8°C. The air temperature at noon is -1.6°C. What is the change in temperature during these three hours right and solve the equation to show your answer then explain what your answer means.

Answer 1

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

Change in temperature = Final temperature - Initial temperature
Change in temperature = (-1.6°C) - (-5.8°C)
Change in temperature = -1.6°C + 5.8°C

Adding a negative number is the same as subtracting a positive number. So, we can rewrite the equation as:

Change in temperature = 5.8°C - 1.6°C
Change in temperature = 4.2°C

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

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