- Cooling Soup When a bowl of hot soup is left in a room, the soup eventually cools down to room temperature. The temperature T of the soup is a function of time t. The table below gives the temperature (in °F) of a bowl of soup t min- utes after it was set on the table. Find the average rate of change of the temperature of the soup over the first 20 min- utes and over the next 20 minutes.
