    I don't see a differential equation, nor to I see an attempted solution. Both of those are required for you to get help here.

    I seriously doubt that you are expected to re-discover Newton's law of cooling. Have a look at that link, then please post your thoughts on how to proceed.

    No, you have to come up the the diffeq, not us!:rolleyes:

    As Tom Mattson said, Newton's law of cooling. It's probably given in your textbook.
