The temperature in Fairbanks, Alaska, fell 10 degrees in 2 hours. Explain why the average temperature change was –5ºF per hour.

5ºF per hour decrease

Step-by-step explanation:

Given that the temperature in Fairbanks, Alaska, fell 10 degrees in 2 hours

For finding average we normally divide the total by number of units

Here change in temperature for 2 days is given as -10 degrees (negative sign is used to denote decrease)

For 2 days change in temperature = -10 degrees F

Hence average change in temperature = change for one day

= -10/2 = -5 degrees F

So answer is 5ºF per hour decrease

Since 10/2 equals 5 the only reasonable answer to ¨Temperature per hour¨ is -5. Also because the temperature dropped 10 degrees in 2 hours which concludes 5 degrees dropped per hour.
