There are two hours between 11am and 1pm. The change in temperature was 60 °F - 40 °F = 20 °F. So the average hourly rate of temperature change was 20 °F / 2 hr = 10 °F/hr. That's change in temperature divided by change in time.

the temperature changed 20 degrees in 2 hours
that is 20 degrees / 2 hours = 10 degrees / hour

In 2 hours, the temperature increased by 20F and so if the increase is uniform, it is 10 degrees Fahrenheit per hour.
