Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between the temperature of the object and the temperature of the environment.

The body of a murder victim was discovered at 11:00 AM. The medical examiner arrived at 11:30 AM and found the temperature of the body was 94.6o F. The room temperature was 70o F. One hour later the body temperature was 93.4o F. Estimate the time of death.
