First you have to figure out the length of the track:

r is the half of the diameter:
200ft : 2 = 100ft

= 200

≈
628,31
The athlete has to run ca. 5280ft for one mile:
5280 : 628,31≈8,4
The athlete has to run 8,4 laps
9/11=x/22
11*2=22
9*2=x
x=18
9/11=18/22
TRUE because 8/15 = 0.53 which is less than 3/5 = 0.60
Answer: The slope is 1/2. The equation for this answer is y= 1/2 r - 2
