= = 09.16.09 Math 7D Problem 2.5 : Day 5 : Norfolk to Williamsburg Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns. Essential Question: What are some situations that we can describe as variable?**
 * S.C

Theo's fastest recorded speed was 20 and it was at 90 minutes. Theo's slowest recorded speed was 15 and it was at 10,30,50 and 70 minutes. In 0 to 70 minutes he had 10 minutes interval but after 70 minutes speed is increase. I think it is number 2. because first time he go faster but last few minutes he can be tired so it might be mumber 2.
 * A. What was Theo's fastest recorded speed, and when did it occur?**
 * B. What was Theo's slowest recorded speed, and when did it occur?**
 * C. Describe the changes in Theo's speed during the race.**
 * D. The graph only shows Theo's speed at 10-minute intervals; it does not tell us what happend between 10-minute marks. The paths below show five possibilities of how Theo's speed may have changed during the first 10 minutes. Explain in writing what each connecting path would tell about Theo's speed.**

1. Would it be possible for the below to represent Theo's progress between 10-minute marks? Why or why not?** It can't posible. because everything in the world that can't just move without time pass. During 30 to 40 minutes periods, it chaged the most.
 * Follow Up
 * 2. During which 10-minute period(s) of the race did Theo's speed change the most?**
