To find the temperature drop per hour, we can use the total temperature drop and divide it by the total time (in hours).
We know:
- Total temperature drop = 12°
- Total time = 5 hours
We can express the change in temperature per hour (x) with the equation:
\[ 5x = 12 \]
Now, we solve for x:
\[ x = \frac{12}{5} \]
Thus,
\[ x = 2.4° \]
This means the temperature decreased by 2.4° every hour.
To complete your statements:
- 5x = 12
- The temperature decreased by 2.4° every hour.
