Math Problem Statement

A body was found in the basement of the Underwater Basket Weaving Building at​ 12:00 noon​ today, where the temperature is a steady 65 degrees Fahrenheit. When​ found, the core temperature was 92.5 degrees Fahrenheit.  Two hours​ later, at​ 2:00 PM, the core temperature had fallen to 88.1.   Assuming that the body temperature was 98.6 at the time of​ death, use​ Newton's law of cooling to find the time of death. 

The tine of death was about how many hours before the body was found
