A cup of coffee at 93 degrees Celsius is placed in a room at 23 degrees Celsius. Suppose that the coffee cools at a rate of 1 degrees Celsius per minute when the temperature of the coffee is 70 degrees. The differential equation describing this has the form dTdt=k(T−A), where A= 23 , and k= -1 . Either from drawing the direction field (try Maple or by hand) or other intuitive means, the limiting value of T should be:
