The graph should show a steady speed, then a decrease in speed during the construction zone, followed by an increase in speed back to the original steady speed. Then, there should be another decrease in speed as he approaches the exit and comes to a complete stop at the stop sign. The graph in choice B accurately represents all of these changes in speed.
