Newton's law of cooling states that the rate at which the temperature of an object changes is directly proportional to the difference in temperature between the object and that of the surrounding medium. A cup of coffee is prepared with boiling water (212 °F) and left to cool on the counter in a room where the temperature is 70 °F. If the temperature of the coffee is 120 °F after 1 min, determine when the coffee will be cool enough to drink (say, 111 °F). ? Round the answer to the nearest tenth, if necessary. ? t = __________ min
