any help would be greatly appreciated.

If you know that the circumference is C=2pi*r where r is the radius, then the total difference between the inside and outside radii is 10*3.4=34in. This means 2pi*r+34=2pi*R where r and R are the inner and outer radii respectively. Note that R-r is the track width.

Thus 34=2pi*R-2pi*r= 2pi(R-r) so

34/(2*pi) = R-r = track width
