The
Race Part 1: Martin Lel
Now
you are finally ready for the big day. The winner of the 2003 New
York City Marathon was Martin Lel of Kenya. In this section of the
race you will collect data from Lel's run, create a graph of his
race, and interpret the graph. In the second section you will compare
P. Diddy's race data to Lel's and in the third section you will
develop data for your own race and compare it to the other two.
Step
1: Collect the Data
Start
by collecting the data on Lel's race. Go the NYC
Marathon Results Page and click on "Results Archive (1970-2004)"
on the left (View Pic).
In the pop-up window select "Show Marathoner History"
and enter the first name "Martin" and last name "Lel"
(View Pic). Click "go"
on the bottom of the pop-up window to see statistics for Lel. Use
this data to fill in the table below in your Race Log (View
Pic).

Step 2: Make
a Graph
Go to http://nces.ed.gov/nceskids/createagraph/
and select "XY" as your graph type. Follow the tabs in
the graph maker to desing your graph. Be sure to choose "line"
as the "XY Type" in the design tab. Give your graph appropriate
tiles and lables. When you are done use the "Print/Save"
tab to save your graph and a .JPG picture and then insert it into
your Race Log. Click
here if to view step-by-step instructions for creating your graph.
DO NOT CLOSE
YOUR GRAPH WINDOW IN CREATE-A-GRAPH. You will be adding data to
the same graph on the next page.
Step 3: Interpret
the graph.
Answer the following
questions about Martin Lel's graph in your Race Log.
1) What is the
shape of the graph?
2) Find the
slope of the graph between the first two points.
3) Find the
slope of the graph between the last two points. How does it compare
to the slope in number 2?
4) What conclusion
can you make about the runner's pace based on the graph? (For example,
were there sections of the race when he ran faster or slower than
other sections?)
5) What do you
think would be a good estimate of Lel's average speed during the
race? Explain how you found your value and why it is appropriate.
