Answer:


129.5\ sec

Explanation:

Step 1

Find the circumference of
40\% of a circle

The formula is equal to


C=0.40(2\pi r)

we have


r=225\ ft

substitute


C=0.40(2\pi (225))=180 \pi\ ft

Step 2

Find the perimeter of the baseball field


P=180 \pi+300*2=1,165.49\ ft

Step 3

Find how long does it take you to run around the baseball field

Divide the perimeter by the rate


t=1,165.49/9=129.5\ sec
