Final answer:
The temperature in Fargo, ND after six hours is -32 degrees Fahrenheit.
Step-by-step explanation:
To find the temperature after six hours, we need to add the change in temperature over the six-hour period to the initial temperature.
The initial temperature in Fargo, ND was -8 degrees Fahrenheit.
Over the six hours, the temperature rose by -4 degrees Fahrenheit per hour.
So, we can calculate the final temperature using the formula:
Final Temperature = Initial Temperature + Rate of Change * Time
Final Temperature = -8 + (-4 * 6)
= -8 + (-24)
= -32 degrees Fahrenheit
Therefore, the temperature after six hours was -32 degrees Fahrenheit.
