In 12 hours, the temperature fell steadily from 17°f to 7°f. what was the average change in temperature per hour?

Step-by-step explanation:

Givens

When the problem says "steadily", it means that the temperature is falling down in a linear way.

Now, to find the rate  between temperature and time, we just need to divide the difference of temperature and the number of hours,

Therefore, the temperature fell 5 °F per every six hours, which is approximately 0.83 °F per hour.
