A detective is called to the scene of a crime where a dead body has just been found. She arrives on the scene at 10:23 pm and begins her investigation. Immediately, the temperature of the body is taken and is found to be 80-F. The detective checks the programmable thermostat and finds that the room has been kept at a constant 68-F for the past 3 days. After evidence from the crime scene is collected, the body's temperature is taken once more and found to be 78.5-F. This last temperature reading was taken exactly a quarter after 11:01 pm. Assuming that the victim's body temperature was normal (98.6-F) before death,
