Irena's Gold
(page 56)
 Here's a solution from a group at Salem Church Middle School, which looks as if it may be in Virginia: The solution to this problem is about 22.6 in the year 1968. We got this answer by taking all the data and plotting it on a piece of graph paper. We put the times on the Y-axis and the years on the X-axis.After all the data was plotted, we looked at when the line crossed the year 1968 and that is about the solution. Cory Seay Steven Whisenand Michael Boyd We are from Salem Church Middle School Teacher: Mr. Twilley And another one; it's not clear where they're from: We did Irena's Gold problem. First, we documented the years and times of the Olympic runs. We put the years on the x-axis and times of the runners on the y-axis. We graphed it both on paper and on the TI-83 graphing calculator. And with the clues given in 1968 she ran a 22.8 second run. Students involved, Brian Harmen Evan Miller Bruce Privott Thank you, both groups! And thank you for your clear description of what you did. So, everyone... how fast did she really run? (It's easy to find on the web. Search for Szewinska.) And what about the difference between the two answers? Finally, what if you include the data from 1996 and 2000? Does that change what you think? Here are those recent results: ```Women's Olympic 200-m 1996 Marie-Jose Perec (France) 22.12 seconds 2000 Marion Jones (USA) 21.84 seconds ``` back to the Answer Book page
