A toy cart accelerates uniformly down a smooth inclined plane, passing four equally spaced markers labeled PPP, QQQ, RRR, and S S\,S in order.
The times taken to travel between consecutive markers are measured. Where is the average speed of the cart the greatest, and between which two markers is the travel time the shortest?
Average speed is greatest between PPP and QQQ; time is shortest between PPP and QQQ
Average speed is greatest between PPP and QQQ; time is shortest between RRR and SSS
Average speed is greatest between RRR and SSS; time is shortest between PPP and QQQ
Average speed is greatest between RRR and SSS; time is shortest between RRR and SSS
