Biking Speed and Data Representation

In Lesson 19, students learn to compare equations, tables, and graphs through a bike race scenario involving Brian, Shanice, and Evelyn. Each uses a different method to track biking rates: Brian uses a table, Shanice a graph, and Evelyn an equation. The lesson guides students to calculate unit rates and determine who is the fastest biker. Brian is the fastest, traveling 25 miles per hour, followed by Evelyn at 20 miles per hour, and Shanice at 15 miles per hour. The lesson emphasizes understanding and comparing different data representations.
