- 6. Module 1 Lesson 4.notebook 6 September 16, 2013 Complete the following class work independently. Which Team Will Win The Race?? • You have decided to run in a long distance race. There are two teams that you can join. • Team A runs at a constant rate of 2.5 miles per hour. • Team B runs 4 miles the first hour and then 2 miles per hour after that. Task: Create a table for each team showing the distances that would be run for times of 1, 2, 3, 4, ,5 and 6 hours.
- 8. Module 1 Lesson 4.notebook 8 September 16, 2013 a. For which team is distance proportional to time? Explain your reasoning. b. Explain how you know distance for the other team is not proportional to time.
- 9. Module 1 Lesson 4.notebook 9 September 16, 2013 c. If the race were 2.5 miles long, which team would win? Explain. If the race were 3.5 miles long, which team would win? Explain. If the race were 4.5 miles long, which team would win? Explain.
- 10. Module 1 Lesson 4.notebook 10 September 16, 2013 d. For what length race would it be better to be on Team B than Team A? Explain e. Using this relationship, if the members on the team ran for 10 hours, how far would each member run on each team?
- 11. Module 1 Lesson 4.notebook 11 September 16, 2013 f. Will there always be a winning team, no matter what the length of the course? Why or why not? g. If the race is 12 miles long, which team should you choose to be on if you wish to win? Why would you choose this team? h. How much sooner would you finish on that team compared to the other team?
- 12. Module 1 Lesson 4.notebook 12 September 16, 2013 Closing How does knowing two quantities are proportional help answer questions about the quantities? For example, if we know 1 cup = 8 oz, what does that allow us to do?
- 13. Module 1 Lesson 4.notebook 13 September 16, 2013 EXIT TICKET Complete the table. If Gabby wants to make an octagon with a side length of 20 inches using wire, how much wire does she need? Justify your reasoning with an explanation of whether perimeter is proportional to the side length. The table below shows the relationship between the side lengths of a regular octagon and its perimeter.
