A dead body was found within a closed room of a house where thetemperature was a constant 70° F. At the time of discovery the coretemperature of the body was determined to be 80° F. One hour latera second measurement showed that the core temperature of the bodywas 75° F. Assume that the time of death corresponds tot = 0 and that the core temperature at that timewas 98.6° F. Determine how many hours elapsed before the body wasfound. [Hint:Let t1 > 0 denote thetime that the body was discovered.] (Round your answer to onedecimal place.)
