Instructions: Walk the following distances (as seen on the data table) and count the time it takes you to reach each distance in your head (“one Mississippi”, “two Mississippi”…etc). BE SURE TO WALK AT THE SAME RATE OF SPEED EACH TIME! Record your time in seconds. Plot your data on a LINE graph (Use Graphical Analysis (GA) to do this). Time is your X-axis. Distance is your Y-axis.
Time (s) Distance (m)
_____s 10 m
_____s 15 m
_____s 20 m
_____s 25 m
_____s 30 m
1. Find the slope of the line between 15 m and 10 m. Remember Slope = y2-y1
2. Find the slope of the line between 20 m and 15 m x2-x1
3. Find the slope of the line between 25 m and 20 m
4. Find the slope of the line between 30 m and 25 m
5. Find the average slope by adding up all of the slopes you found in questions #1-4 and divide by 4.
6. The average slope should tell you how many meters you walk in (choose one)
a) one second b) two seconds c) three seconds d) four seconds
7. If you were to walk for 50 seconds, how many meters would you travel? (use your average slope to figure this out).
8. If you were to walk for 100 seconds, how many meters would you travel?
9. If you were to walk for one hour, how many meters would you travel? (you will have to figure out how many seconds are in one hour).
10. If you were to walk 5000 meters, how long would it take you in seconds?
11. If you were to walk 10,000 meters, how long would it take you in seconds?
12. How fast do you walk in miles per hour? To find out, multiply your slope by 2.22
