A 2-ft wide circular track for a camera dolly is set up for a movie scene. The two rails of the track form concentric circles. The radius of the
inner circle is 64 ft. How much farther does a wheel on the outer rail travel than a wheel on the inner rail of the track in one turn?
The wheel on the outer rail travels ____ feet farther than the wheel on the inner rail of the track in one turn.
