Answer:
C:Peter walks at a rate of 13/4 miles per hour.
Step-by-step explanation:
The equation used to model the number miles walked by Peter after x hours is
(1)
where
x is the number of hours
y is the number of miles walked
For an object moving in uniform motion (=at constant velocity), the distance covered in a time t can be written as
(2)
where
d is the distance covered
v is the velocity
t is the time
By comparing eq(1) and eq(2), we notice that the two are the same, if we put
which means that Peter's velocity is 13/4 miles per hour. Therefore, the correct option is
C:Peter walks at a rate of 13/4 miles per hour.
