Question

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 1

did u explain what the answer means

Answer 2

To find the change in temperature, we need to subtract the initial temperature from the final temperature.
Final temperature: -1.6 degrees Celsius
Initial temperature: -5.8 degrees Celsius

Change in temperature = Final temperature - Initial temperature
Change in temperature = (-1.6) - (-5.8)

To simplify, we can change the subtraction of two negative numbers to addition, and so:
Change in temperature = (-1.6) + 5.8

Adding the numbers, we get:
Change in temperature = 4.2 degrees Celsius

The change in temperature during these three hours is 4.2 degrees Celsius.

This means that the temperature increased by 4.2 degrees Celsius between 9 a.m. and noon.

Answer 3

Apologies for the oversight. The answer, 4.2 degrees Celsius, represents the change in temperature during the three-hour period from 9 a.m. to noon. More specifically, it indicates the increase in temperature from -5.8 degrees Celsius at 9 a.m. to -1.6 degrees Celsius at noon. The positive value of the change in temperature indicates a rise in temperature. Therefore, the air temperature increased by 4.2 degrees Celsius over the span of three hours.
