Question

A turkey 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?

Answer 1

The Answer is 42° F.
The difference in Temperature is 156-30=126.
Which mean 126 was the increase in Temperature in 3 hours.
So the Temperature increase in one hour would 126/3 = 42.

Hope this helps :)

Answer 2

Given,

The turkey was roasted in the stove for 3 hours.

The inner heat rose from 30 degrees F to 156 degrees F.

The average increase in heat per hour = Total rise in temperature/ total number of hours

The 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 hour

                                                               = 42 degrees F/hour
