Aturkey was cooked at 400 f in the oven for 3 hours. the internal temperature rose from 30 f to 156 f. what was the average rise in temperature per hour

Given,
The turkey was cooked in the oven for 3 hours.
The internal temperature rose from 30 degress F to 156 degrees F.

Average rise in temperature per hour = Total rise in temperature/ total number of hours

Average rise in temperature = 156 degrees F – 30 degrees F= 126 degrees F

Total number of hours = 3 hours

Average rise in temperature per hour = 126 degrees F/3 hours= 42 degrees F/hour
