Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton's law of cooling. If the coffee has a temperature of 185 degrees Fahrenheit when freshly poured, and 2 minutes later has cooled to 170 degrees in a room at 72 degrees, determine when the coffee reaches a temperature of 130 degrees. The coffee will reach a temperature of 130 degrees in ? minutes
