Two athletes start a race at the same time. The functions \( p(x)\) and \( t(x)\) give the distance in meters that each run after \(\mathbf{x}\) seconds. What does \( p(8)- t(8)=2\) mean in this context? The runners are 2 meters apart 8 seconds after the race starts The runners are 8 meters apart 2 seconds after the race starts Both runners travel 2 meters in the first 8 seconds of the race Both runners travel 8 meters in the first 2 seconds of the race
