A dead body was found within a closed room of a house where the temperature was a constant 70◦F . At the time of discovery the core temperature of the body was determined to be 85◦F . One hour later a second measurement showed that the core temperature of the body was 80◦F. Assume that the time of death corresponds to t = 0 and the core temperature at the time was 98.6◦F. Determine how many hours elapsed before the body was found. (Use Newton’s Law of Cooling and let t1 > 0 denote the time that the body was discovered

Question
A dead body was found within a closed room of a house where the temperature was
a constant 70◦F . At the time of discovery the core temperature of the body was
determined to be 85◦F . One hour later a second measurement showed that the core
temperature of the body was 80◦F. Assume that the time of death corresponds to t = 0
and the core temperature at the time was 98.6◦F. Determine how many hours elapsed
before the body was found. (Use Newton’s Law of Cooling and let t1 > 0 denote the
time that the body was discovered
