First let's find the number of hours from 6AM to 12PM.
The difference of hours between these times is 6 hours, so the amount of hours is 6.
Then, to find the average hourly drop in temperature, we just need to divide the temperature change by the number of hours passed, so we have:
[tex]\frac{14}{6}=\frac{7}{3}[/tex]So the average hourly drop in temperature was 7/3 °F per hour.
