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.
Add 1.34 to the other side. and subtract those two numbers to get P
I sent the solution along with explanations.
Answer:
it's hard to tell the exact question being asked...
y = 
or
y = 
if y =
then Domain is [0 ,∞ )
if y =
then Domain is [-1 ,∞ )
