Solve the following word problem. The air temperature at 9 AM is -5.8°C. The air temperature at noon is -1.6°C. What is the change in temperature during these three hours right and solve the 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
Change in temperature = (-1.6°C) - (-5.8°C)
Change in temperature = -1.6°C + 5.8°C
Adding a negative number is the same as subtracting a positive number. So, we can rewrite the equation as:
Change in temperature = 5.8°C - 1.6°C
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2°C.
This means that the temperature increased by 4.2 degrees Celsius from 9 AM to noon.
To find the change in temperature, we need to subtract the initial temperature from the final temperature.
Final temperature at noon: -1.6°C
Initial temperature at 9 AM: -5.8°C
Change in temperature = Final temperature - Initial temperature
Change in temperature = (-1.6°C) - (-5.8°C)
To subtract a negative number, we can change the signs and add the numbers:
Change in temperature = -1.6°C + 5.8°C
Now we can add the numbers:
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2°C. This means that the temperature has increased by 4.2 degrees Celsius from 9 AM to noon.
