The temperature of a pot of water fell from 72°F to 36°F in 4 minutes. Find the average temperature change per minute.

If the temperature falls from 72°F to 36°F in four minutes, it means it fell 72-36 = 36°F in four minutes.
To find out what's the value of the temperature fall in one minute we just have to divide 36 by 4:
36 / 4 = 9
Answer: The temperature fell 9°F per minute.
