In an experiment, a heated cup of coffee is removed from a heat source, and the cup of coffee is then left in a room that is kept at a constant temperature. The graph above shows the temperature, in degrees Fahrenheit `(.^@F)`, of the coffee immediately after being removed from the heat source and at 10-minute intervals thereafter.
During which of the following 10-minute intervals does the temperature of the coffee decrease at the greatest average rate?

The graph above shows the temperature, in degrees Fahrenheit (.^@F) , of the coffee immediately after being removed from the heat source and at 10-minute intervals thereafter. Of the following, which best approximates the temperature, in degrees Fahrenheit, of the coffee when it is first removed from the heat source?
