Problem 2.3 AM

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?
 * *This graph does not show total distance. It shows how close the riders were to their destination at the time.* **
 * A. Would it make sense to connect the points on this graph? Explain **

A. I think it would make sense to connect the points on the graph, to see if the riders were closer to their destination.

B.
 * B. Make a table of (time, distance) data from the information. **
 * Time || Distance ||
 * 0 || 0 ||
 * 0.5 || 8 ||
 * 1 || 13 ||
 * 1.5 || 22 ||
 * 2 || 22 ||
 * 2.5 || 30 ||
 * 3 || 22 ||
 * 3.5 || 31 ||
 * 4 || 38 ||
 * 4.5 || 49 ||
 * 5 || 49 ||
 * 5.5 || 58 ||
 * 6 || 64 ||
 * 6.5 || 72 ||
 * 7 || 74 ||
 * 7.5 || 82 ||


 * C. What do you think happened between hours 2 and 4? Between hours 1.5 and 2? **

C. In hours 1.5-2, they might have stopped to take a break. During hours 2-4, they went to ride again, but they left something, where they stopped, and they had to go back.


 * D. Which method of displaying the (time, distance) data helps you see the changes better, a table or a graph? Explain your choice. **

D. I think a table helped me see the changes more accurately, but I could see the changes more clearly on a graph.

Follow- Up · I added 82, as that was the most distance they made in 7.5 hours, to 16, because they had to go back 8 miles, and then come forward 8 miles. So, this adds up to a total 98 hours.
 * Use the graph to determine the total distance the riders traveled in on day 3. Explain how you determined your answer. **
