The Deep Freeze


You and your friends are making ice cream. You are observing (at 60 second intervals) the temperature of the mixture for a science project. When you start the solution is at 65 degrees F. When frozen, the ice cream is at 25 degrees F. However, you missed recording some of the temperatures. Here is the data you collected:

24 25

How can you estimate the temperature after 1 minute and after 2 minutes? What were the temperatures? Explain your reasoning.
