A roast was cooked at 325 °F in the oven for 4 hours. The internal temperature rose from 32 °F to 145 °F.What was the average rise in temperature per hour?
It has a rather very easy solution. First find the temperature difference between the the initial and final internal temperatures which is 145 - 32 = 113 F. The time span is about 4 hours, divide 113 F by 4 , which is 28.25 F per hour.
