Activity 13.1: Rates - Line Graph and Table of Values
YOUR TASK
The line graph and table provide data. Use this information to answer the following questions. This GeoGebra applet displays a line graph showing the distance traveled (in meters) by a biker over time (in minutes). A corresponding table of values is also available, which can be viewed by selecting the CHECKBOX next to it.
You can investigate a specific duration by entering the start and end times in the INPUT BOXES. The applet will then highlight the corresponding point on the line graph and display the distance traveled during that time.
ANALYZING DATA
What is the biker's rate of distance per time travelled in the whole trip?
ANALYZING DATA
What is the biker's rate of distance per time travelled in the first ten minutes of the trip?
ANALYZING DATA
What is the biker's rate of distance per time travelled in the last ten minutes of the trip?
ANALYZING DATA
At which duration did the biker travel at the lowest rate of distance per time?
ANALYZING DATA
At which duration did the biker travel at the highest rate of distance per time?
SYTHESIS QUESTION
Based on the data from the line graph and table, explain how the biker's speed changes over time. What evidence from the graph or table supports your conclusion?
