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
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
In this case,
Final temperature = −1.6 degrees Celsius
Initial temperature = −5.8 degrees Celsius
Change in temperature = −1.6 - (−5.8)
= −1.6 + 5.8
= 4.2 degrees Celsius
Therefore, 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.
To find the change in temperature during these three hours, we need to subtract the initial temperature from the final temperature.
Let's denote the initial temperature at 9 a.m. as T1 and the temperature at noon as T2.
T1 = -5.8 degrees Celsius
T2 = -1.6 degrees Celsius
The change in temperature is given by the equation ΔT = T2 - T1.
Substituting the values, we have:
ΔT = (-1.6) - (-5.8)
ΔT = -1.6 + 5.8
ΔT = 4.2 degrees Celsius
Therefore, 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.
To find the change in temperature during these three hours, we need to calculate the difference between the temperature at 9 a.m. and the temperature at noon.
The temperature at 9 a.m. is -5.8 degrees Celsius, and the temperature at noon is -1.6 degrees Celsius.
To find the change in temperature, we subtract the initial temperature (9 a.m. temperature) from the final temperature (noon temperature).
Change in temperature = Final temperature - Initial temperature
Change in temperature = (-1.6) - (-5.8)
To solve this equation, we need to subtract -1.6 from -5.8.
Change in temperature = 4.2 degrees Celsius
Therefore, 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.
