To determine the amount of change in temperature every hour, we can set up the equation based on the given information.
If the total temperature drop is 12° over 5 hours, we can represent the amount of change in temperature per hour as \( x \).
Since the temperature dropped the same amount every hour, we can write the equation like this:
\[ 5x = 12 \]
Now, to solve for \( x \):
- Divide both sides of the equation by 5:
\[ x = \frac{12}{5} \]
- Simplifying the fraction:
\[ x = 2.4 \]
So, the completed equation is:
\[ 5x = 12 \]
The temperature decreased by 2.4° every hour.
To summarize:
- The completed equation: 5x = 12
- The temperature decreased by 2.4° every hour.
