The average change in temperature per hour is 0.833 degrees per hour
Solution:
Given that In 12 hours the temperature steadily fell from 17°F to 7°F
To find: Average change in temperature per hour
First let us calculate the difference when temperature steadily fell from 17°F to 7°F
The difference from 17 degrees to 7 degrees is given as:
difference = 17 - ( 7) = 17 - 7 = 10 degrees
And it took 10 hours for such a change to happen.
Now let us find the average change in temperature per hour
Average change in temperature per hour is calculated by dividing 10 degrees by 12 hours
[tex]\text{ Average change in temperature per hour } = \frac{ \text{ 10 degrees }}{12 \text{ hours }}[/tex]
[tex]\rightarrow \frac{ \text{ 10 degrees }}{12 \text{ hours }} = 0.833 \text{ degrees per hour }[/tex]
Thus the average change in temperature per hour is 0.833 degrees per hour
