Question

In 12 hours the temperature steadily fell from 17°F to 7°F. What was the average change in temperature per hour?

Answer 1

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

`\text{ Average change in temperature per hour } = \frac{ \text{ 10 degrees }}{12 \text{ hours }}`

`\rightarrow \frac{ \text{ 10 degrees }}{12 \text{ hours }} = 0.833 \text{ degrees per hour }`

Thus the average change in temperature per hour is 0.833 degrees per hour
