I think that it is saying that 8:15-8:45 is 7.5 miles right? Then 8- 8:15 is 4.5 and you are trying to find the average of an HOUR.
So in order to get an hour you need 15 more mins. Which is 4.5 miles
according to the chart. (8-8:15). So 4.5+4.5+7.5=16.5. Divided by three
is 5.5 miles per hour. I'm not sure but this is what I would do.
