We are given with the data that at 10 am, the temp is 40oF. We are asked for the time when the body's temperature is equal to 80oF. In this casem we use Newtons law of cooling: T (t) = Ta + (To - Ta) e -kt. Substituing, 98.6 = 40 + (80-40) e -0.1947t. t is equal to . Hence the approximate time of death is -1.96 hrs ago or approx two hours ago. The answer is 8 am.
