Suppose that a cup of soup cooled from 90 °C to 60 °C after 15 minutes in a room whose temperature was 20 °C. Use Newton's law of cooling to answer the following questions.
(a) How much longer would it take the soup to cool to 45 °C?
(b) Instead of being left to stand in the room, the cup of 90 °C soup is put in the freezer whose temperature is - 15 °C. How long will it take the soup to cool from 90 °C to 45 °C?

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

its c or d   take a lucky guess my dude

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
