The temperature changed from 7°f at 6pm to -5°f at midnight. What was the difference between the high an low temperatures? Whats was the average change in temperature per hour?

Answer 1

Difference between high and low temperatures: 12°F

Average change in temperature per hour: 2°F

Explanation:

The difference between high and low temperatures was: 7 - (-5) = 12 (°F)

Midnight is 12am, so 6pm to midnight is 6 hours.

The average change in temperature per hour is: 12 / 6 = 2 (°F)
