There are five hours between 11:00 a.m. and 4:00 p.m.
.
During that time the temperature went from 44�F to 54�F, a change of +10�F.
.
The average hourly rate of change is the change in temperature divided by the change in time:
.
Rate = 10�F/5 hr = +2�F/hr
.
The rate of change is read as +2�F per hour with the + sign indicating that the temperature
was increasing each hour.
.
Note this is the "average" rate for the entire period of 5 hours. In "real life" the temperature
might not have changed during the first couple of hours and then it could have increased
at a faster rate during the last hour or two ... just enough to make the total change 10�F
by the end of the 5 hours.
.
Hope this helps you to understand the problem.
