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.

Answer:

Average temperature = 9°F per minute

Step-by-step explanation:

Given : the temperature of a pot of water fell from 72°F to 36°F in 4 minutes.

To find : Find the average temperature per minute.

Solution : We have given

Temperature decreases in 4 minute =  72°F to 36°F

72 -36 = 36°F

Temperature decreases in 4 minute =  36°F

Temperature decreases in 1 minute =  [tex]\frac{36}{4}[/tex].

Temperature decreases in 1 minute =  9°F

Average temperature =  [tex]\frac{9}{1}[/tex].

Average temperature = 9°F per minute.

Therefore,  Average temperature = 9°F per minute.
