If the path of the runner running at a greatest radius of 20 m is 100 m long, how far behind in m should the runner at the smallest radius start? The smallest radius is 15 m.

**bobpursley**, Wednesday, September 25, 2013 at 10:11amdistance will be proportional to radius.

(perimeterofCircle=PI*2*radius)

difference in perimeters=2PI*(20-15)

so that distance is the how far behind should the inner radius be.
