Two cars travel on a straight road from point A to point B. Both cars accelerate to their maximum speed and then continue at that speed for the rest of the distance. Car 1 accelerates from rest to 20 m/s over 30 s. It reaches point B in 35 s. Car 2 accelerates from rest to 20 m/s over 20 s. It reaches point B in 30 s. Which car uses a larger acceleration to reach its maximum speed, and which car has a larger average speed?
