Unit 5 Contents

1. Describe the graph. What does the graph tell you about the relationship between time and distance?

2. How would a change in time affect distance?
3. How would a change in distance affect time?
11. Use your graph to find the time taken to walk 8 yards.
12. Find the distance walked after 10 seconds.
1. Give your answer in yards.
2. Give your answer in feet.
1. Choose a point on the line and use it to write the walker's speed as a ratio of distance traveled to time taken, written as a fraction.
2. Choose two more points on the line and use them to write two ratios equal to the ratio in Question 13A.
1. How many yards did the walker travel in one second?
2. Give the walker's speed in yards per second (yards/second).
1. How many feet does the walker travel in one second?
2. Give the walker's speed in feet per second (feet/second).

Check-In: Question 16

16. If the walker in your experiment continues at the same pace for one hour, about how far will he or she walk? Show or tell how you used your data to answer the question.
17. Do you think the walker can walk at the same speed you calculated in Questions 14 and 15 for one hour or longer? Why or why not?
18. There are 5280 feet in a mile. About how many miles can the walker walk in one hour? How do you know?
