In a lab, a substance was cooked by 42 c over a period of 7 hours at a constant rate. what was the change in temperature each hour

Given that we have the change in temperature over 7 hours and we are looking for the change over 1 hour, we can divide the total change in temperature by 7. Thus, the change in temperature would be .

Additionally, this can be solved by equations:

By using two different methods, we can determine that the change each hour was equal to 42/7 C° per hour.
