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.


my answer is "To find the change in temperature, we need to find the difference between -5.8 and -1.6. We can do this by either counting to the left of 0 on a number line, or we can subtract 1.6 from 5.8. To find the difference between the two numbers, we just subtract the smaller number from the bigger number, as you would if they were positives. 5.8 - 1.6 = 4.2. The change in temperature is 4.2 degrees Celsius." is that correct?

Answer 1

Just a warning for anyone viewing this question, PLEASE dont copy my answer! im just here to explain how to find the answer.

Answer 2

Yes, your answer is correct. The change in temperature during the three hours is 4.2 degrees Celsius. It shows that the temperature increased by 4.2 degrees Celsius from -5.8 degrees Celsius at 9 a.m. to -1.6 degrees Celsius at noon.

Answer 3

Apologies if my initial response could be misunderstood. I understand that the purpose is to explain how to find the answer rather than simply providing it. To solve the word problem, you need to find the difference between the air temperature at 9 a.m. and the air temperature at noon.

To calculate the change in temperature, you subtract the initial temperature from the final temperature. In this case, the initial temperature is -5.8 degrees Celsius, and the final temperature is -1.6 degrees Celsius.

So, the equation to calculate the change in temperature is:

-1.6 - (-5.8) = -1.6 + 5.8

Performing the arithmetic:

-1.6 + 5.8 = 4.2

The change in temperature during these three hours is 4.2 degrees Celsius. This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
