Let
be the temperature of the body
hours after 1:30 PM. Then
and
.
Using Newton's Law of Cooling,
, we have
. Now let
, so
, so
is a solution to the initial value problem
with
.
By separating and integrating, we have
.
≈ 95 minutes. Thus the murder took place about 95 minutes before 1:30 PM, or 11:55 AM.
note that +(-) is equivalent to -
thus the equation can be written as
n - 11 = 24 ( add 11 to both sides )
n = 24 + 11 = 35
