Question

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

Answer 1

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 2

Average temperature = 9°F per minute

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 =
`(36)/(4)`.

Temperature decreases in 1 minute = 9°F

Average temperature =
`(9)/(1)`.

Average temperature = 9°F per minute.

Therefore, Average temperature = 9°F per minute.
