Answer 2

Solve the following word problem. 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? Write and solve an equation to show your answer. Then explain what your answer means.

Answer 3

To find the change in temperature during the three hours from 9 a.m. to noon, we can subtract the temperature at 9 a.m. from the temperature at noon.

Change in temperature = (Temperature at noon) - (Temperature at 9 a.m.)

Given:
Temperature at 9 a.m. = -5.8 degrees Celsius
Temperature at noon = -1.6 degrees Celsius

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

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

This means that the temperature has increased by 4.2 degrees Celsius from 9 a.m. to noon.
