In agreement with Jenny. The green car overall has the highest ending velocity, but although the pink and blue car had greater acceleration rates, the ending velocity was nowhere near the same.
Pat thinks the cars stop at 17 seconds because the last car no longer accelerates after 17 seconds. He is not aware that although the cars are no longer accelerating, it does not necessarily mean that the cars are not moving. Velocity still exists however there is no change.
The pink car has the greatest change in position during the time interval t=3 and t=5. The reason for this is because the pink car's velocity is 30 m/s while the others are only 12 m/s (Green) and 15 m/s (Blue)
