Question 925770: Police arrive at a murder scene at 2:00 AM and immediately record the body’s temperature which was 90 degrees Fahrenheit. At 2:30 AM, after thoroughly inspecting and fingerprinting the area, they again took the temperature of the body which had dropped to 82 degrees Fahrenheit. The temperature of the crime scene has remained at a constant 78 degrees Fahrenheit. Determine when the person was murdered. (Assume that the victim was healthy at the time of death. That is, assume that the temperature of the body at the time of death was 98.6 degrees Fahrenheit.) Do not round until final answer then round to the nearest minute as needed.

You can put this solution on YOUR website! (2:00, 90)
(2:30), 82)
Losing 8 degrees every 30min
....
y = (-8/30)x + 90
98.6 = (-8/30)x + 90
-30/8(96.8 - 90) = x = -26 min
1:34 Time of death
