The air temperature at 9 am 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?
To find the change in temperature, you need to subtract the initial temperature from the final temperature.
The change in temperature is -1.6 degrees Celsius minus (-5.8) degrees Celsius, which is equal to -1.6 + 5.8 = 4.2 degrees Celsius.
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
To find the change in temperature during the three hours, you can subtract the initial temperature from the final temperature.
The initial temperature at 9 am is -5.8 degrees Celsius.
The final temperature at noon is -1.6 degrees Celsius.
To find the change in temperature, subtract the initial temperature from the final temperature:
Change in temperature = Final temperature - Initial temperature
Change in temperature = -1.6°C - (-5.8°C)
To subtract a negative number, you can change the subtraction into addition:
Change in temperature = -1.6°C + 5.8°C
Now, add the numbers:
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
