Summarize It! 1. Construct and Present Arguments A distance-time graph shows the motion of two bicycle riders. Each rider's motion is represented on the graph by a diagonal line sloping upward from left to right. The graph shows that they traveled the same distance. However, the line representing the motion of Rider \#1 slopes upward more steeply than the line representing the motion of Rider \#2. Sketch a graphical model of the motions of the riders. Develop an argument on which rider arrived at his or her destination first. How do you know? Use evidence to add validity to your argument.

**Summary:** The problem involves analyzing a distance-time graph that depicts the movements of two bicycle riders, Rider #1 and Rider #2. Both riders travel the same distance, represented by diagonal lines rising from left to right on the graph. However, Rider #1's line has a steeper slope compared to Rider #2's line. The task is to: 1. **Sketch the Graphical Model:** Draw the distance-time graph illustrating both riders' motions, highlighting the difference in slopes. 2. **Develop an Argument:** Determine which rider reached the destination first based on the graph. 3. **Provide Evidence:** Use the slope differences as evidence to support the conclusion about which rider arrived first. **Key Points:** - Steeper slope indicates a faster rate of travel. - Since Rider #1 has a steeper slope, they maintained a higher speed. - Therefore, Rider #1 likely arrived at the destination before Rider #2.
