A dead body was found within a closed room of a house where the temperature was a constant 21° C. At the time of discovery the core temperature of the body was determined to be 29° C. One hour later a second measurement showed that the core temperature of the body was 27° C. Assume that the time of death corresponds to t=0 and that the core temperature at that time was 37° C. Determine how many hours the body has been dead before the body was found
