dt Governed by Newton's Law of Cooling [= k(Te − T) where T is the temperature of the object, Te is the temperature of the environment, k is the proportionality constant, and time t], an object having a temperature of 90° F is placed in an environment kept at 60° F; and cooled to 88° F after 10 minutes. What will be the temperature of the object after 20 minutes in the same environment? Hint/Notes: When an equation has an absolute value, two scenarios may be placed/set for the equation.
