Terry will be at 60 meters after one minute, Jade will be at 120 meters after one minute, and Jerome will be at 150 meters after one minute. There are 60 meters between Terry and Jade, 30 meters between Jade and Jerome, and finally, 90 meters between Jerome and Terry. Terry will take 750 seconds (12.5 minutes) to get to the yogurt shop. Jade will take 375 seconds (6.15 minutes) to get to the yogurt shop. Jerome will take 300 seconds (5 minutes) to get to the yogurt shop from school. Terry will be 450 meters apart when Jerome arrives at the yogurt shop. **Follow Up: 2.1** I used Unit rates, and linear relationships. Yes, it did involve linear relationships because the interval between the numbers had a unit rate and could be formed into a straight line.
 * A. If Terry, Jade, and Jerome leave school together and walk toward the frozen yogurt shop at the rates given in the table, how far apart will they be after one minute?**
 * B. If the yogurt shop is 750 from school, how long will it take each student to walk there?**
 * C. When Jerome arrives at the yogurt shop, how far away will Terry be?**
 * 1. In problem 2.1, what strategies did you use to get your answers?**
 * 2. Does Problem 2.1 involve linear relationship? Explain why or why not.**
