At 10:30 AM, detectives discover a dead body in a room and measure its temperature at 26 C. One hour later, the body's temperature had dropped to 24. 8 C. We want to determine the time of death (when the body temperature was a normal 37 C) assuming that the temperature in the room was held constant at 20 C, write a differential equation with initial conditions associated with this problem. Clearly state your variables with what they represent.
