Solve the following word problem. The air temperature at 9a.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
To find the change in temperature during these three hours, we need to subtract the temperature at 9 a.m. from the temperature at noon.
The equation to find the change in temperature is: Change in temperature = (Temperature at noon) - (Temperature at 9 a.m.)
Change in temperature = (-1.6) - (-5.8)
Change in temperature = -1.6 + 5.8
Change in temperature = 4.2
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
This answer means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
To find the change in temperature during the three hours, we need to subtract the initial temperature from the final temperature.
The initial temperature at 9a.m. is -5.8 degrees Celsius, and the final temperature at noon is -1.6 degrees Celsius.
Change in temperature = Final temperature - Initial temperature
Change in temperature = (-1.6) - (-5.8)
To subtract a negative number, we can change the subtraction into addition:
Change in temperature = (-1.6) + 5.8
Now, let's calculate this:
Change in temperature = 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 9a.m. to noon.
