A pan of cold water with a temeprature of 35 degrees F is brought into a room with a temperature of 75 degrees F. After one hour, the temperature in the pan is 45 degrees F. a) Write a formula for the temperature (T) as a function of time (according to Newton's Law of Cooling). b) Find the temperature of the water after 3 hours. c) how long will it take the water in the pan to reach 60 degrees F, counting since the moment it was brought into the room.
