There are four cars lined up on a drag racetrack. Their colors are Red, Green, Blue, and Yellow. The length of the track is the NHRA standard, or feet. The Red car finishes first, the Green car is second, Blue is third, and Yellow takes last place. The Red car finishes the track feet ahead of the Green car. The Green car finishes the track feet ahead of the Blue car. If the Blue car finishes the track feet ahead of the Yellow car, what is the position of the Yellow car when the Red car crosses the finish line?
