Passage Summary: Even though the government forced cars to drive slower on a major highway, people actually got to their destinations faster than before.

Reasoning: Lowering the maximum speed limit during rush hour resulted in faster overall travel times for commuters.

Analysis: The paradox here is that a lower speed limit—which intuitively should slow people down—actually resulted in faster travel times. To resolve this, we need a piece of information that explains how driving slower could increase efficiency. Perhaps the lower limit reduced the frequency of accidents that cause massive delays, or it smoothed out the 'stop-and-go' traffic flow that often plagues high-speed roads during rush hour. Look for an answer that addresses the mechanics of traffic flow rather than just the speed of individual cars.
