−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 air temperature at noon from the air temperature at 3 pm.
Temperature change = −5.8 degrees Celsius − (−1.6 degrees Celsius)
To simplify the subtraction, we can first change the signs:
Temperature change = −5.8 degrees Celsius + 1.6 degrees Celsius
Now we can add the temperatures:
Temperature change = −4.2 degrees Celsius
Therefore, the change in temperature during these three hours is −4.2 degrees Celsius.
This means that the temperature dropped by 4.2 degrees Celsius from noon to 3 pm.
To find the change in temperature during these three hours, we need to subtract the initial temperature from the final temperature.
Let's let T0 be the initial temperature at noon and T1 be the temperature three hours later.
Given that the initial temperature T0 is −1.6 degrees Celsius and the final temperature T1 is −5.8 degrees Celsius, we can set up the equation:
Change in temperature = T1 - T0
Plugging in the values:
Change in temperature = (-5.8) - (-1.6)
Simplifying:
Change in temperature = -5.8 + 1.6
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 decreased by 4.2 degrees Celsius during these three hours.
To find the change in temperature during these three hours, we need to subtract the initial temperature from the final temperature.
The initial temperature at noon is -1.6 degrees Celsius, and the final temperature after three hours is -5.8 degrees Celsius. To find the change in temperature, we subtract the initial temperature from the final temperature:
Change in temperature = Final temperature - Initial temperature
Change in temperature = (-5.8) - (-1.6)
To subtract a negative number, we can rewrite it as adding the opposite:
Change in temperature = (-5.8) + 1.6
Now, we can simply subtract the two values:
Change in temperature = -4.2 degrees Celsius
The change in temperature during these three hours is -4.2 degrees Celsius.
Negative change in temperature indicates a decrease in temperature over the three-hour period. In this case, the temperature dropped by 4.2 degrees Celsius.
