Question

Mr. Boddys body is discovered in a walk-in freezer that is held at 34 degrees F: His body has a temp. of 42 degrees F. An hour later, his body cools to 38 degrees F. Find how long ago Mr. Boddy died from the initial time that he was discovered. (Hint:Make t=0 the time the body is 42 degrees F.) [Assume that living persons have a body temp of 98.6 degrees F]

Ans: t= (ln(64/8))/(ln(0.5)) approx. -3.013 so about 3 hrs. ago

Please solve with newtons law of cooling for ordinary diff equations, show all work especially how to find k!
