Two kids decide to race from one end of a 20 meter long moving sidewalk to the other and back. Phillip runs on the sidewalk at 2.0 meters/sec (relative to the sidewalk). Renee runs on the floor at 2.0 meters/sec. The sidewalk moves at 1.5 meters/sec relative to the floor. Both make the turn with no loss of speed. Who wins the race?
