Question

A coroner arrives at a murder scene at 10p.m. She finds the temperature of the body to be 86.3 degrees F. She waits one​ hour, takes the temperature​ again, and finds it to be 83.3 degrees F. She notes that the room temperature is 69 degrees F. Assuming that the temperature of the body was 98.6F when the murder​ occurred, when was the murder​ committed?
Give an aproximate hour and tell weather it was p.m or a.m.

Answer 1

5 - 6 pm

if the temperature drops 3 degrees per hour. so how many hours would it take to go from 98.6 to 86.3

98.6-86.3=12.3

3 goes into 12 4 times.

10 pm - 4 hours is 6pm.

if you figure in the .3

you come to approximately 5pm
