Draw a Picture #2

Billy, Ray, Gary, Clayton, Floyd and Pete just completed a 3000 meter race. Use these clues to help you determine the order in which they finished.

Floyd finished 10 seconds behind Gary.
Ray beat Pete by 20 seconds.
Billy finished 4 seconds behind Gary and 30 seconds ahead of Ray.
Clayton's finish was halfway between Floyd and Pete.

It doesn't look like it, but the best way to solve this problem is to draw a diagram or picture of how the racers finished. Each clue will help with the ordering. Just put the boys in the diagram one (or two) at a time.
As always, be sure to explain the work you did to arrive at your answers!
