4.2+Writing+Stories+to+Match+Graphs

September 16, 2008 SMJ Big Idea: Many real world situations can be modeled and predicted using mathematics. Essential Question: How can I explore patterns in the world? **__ 4.2 Writing Stories to Match Graphs __** Notes from Class: No notes are taken **__ Problem 4.2 __** I think the graph B best represents what might really happen. Because in this kind of situation, most of the drivers don't actually stops for the bus. They just go pass the bus. **__ Problem 4.2 Follow-Up __** Answer. In graph E, the car reaches the greatest speed. Because it's slope at the beginning interval of graph E is the highest of any other intervals in the other graphs. Which means it traveled long distance in a short time which explains the speed of the car is the fastest of the other graphs. Answer. In graph E, the bus reaches the greatest speed. Because it’s slope at the beginning interval of graph E is the highest of any other intervals in the other graphs.
 * Graphs A-F show six possibilities for what might happen at some point after the passenger boards the bus. Each graph shows the relationship between time and distance from the bus station for the bus and the car. For each graph, make up a story about the bus and the car that matches the information in the graph. **
 * A. ** As the bus departed, the car followed the bus.
 * B. ** The car went past the bus in high speed, and the bus departed slowly and stopped to take the passengers.
 * C. ** As the bus departed slowly, the car just went past the bus in high speed.
 * D. ** As the bus departed, the car followed it, and as the bus stopped, the car also stopped.
 * E. ** The bus departed, the car went past the bus in the high speed and stopped, the bus went past the car and stopped to take passengers, and the car went past the bus in high speed.
 * F. ** The bus stopped to take passengers, and the car stopped also.
 * Which graph do you think best represents what might really happen? If none of the graphs seem correct, sketch a graph of what you think is likely to happen. **
 * 1.  **** In which graph does the car reach its greatest speed? Explain how you know. **
 * 2.  **** In which graph does the bus reach its greatest speed? Explain. **
