To answer this question you will compare the distance you walked (0.85 miles) to the distance your friend walked (half the circumference of the circle; C = pi x d/2

Your friend walked 3.14 x 0.85/2 = 1.33 miles approximately

To find the difference in the distances, subtract 1.33 and 0.85.

1.33 - 0.85 = 0.48 miles

Your friend walked 0.48 miles further.
