Thorpe has more in store: Frost



1. What do the following terms mean?

2. Referring to the statistics for Ian Thorpe, why do you think there is a difference in

for the 200 metre final and the 800 metre final.'

3.Using the average Velocity of Ian Thorpe for the 200 metres, how far could he swim in 10 minutes, 15 minutes, and 17 minutes 30 seconds?

4. Using the qverage velocity for Ian Thorpe in the 800 metres, how far could he swim in 5 minutes, 12 minutes 15 seconds, and 22 minutes?

5. If Ian swam for 22 minutes do you think he could actually swim as far as you calculated? Why or Why not?

6. How can you best present all the information for chart 2 in a graphical format?

7. What other factors not mentioned in the statistics may influence Ian Thorpe's speed?

8. What do the numbers 7:41.59 represent? If you were to triple these what would be the result? (Be careful now)

9. Compare your foot size to Ian Thorpe's foot size (17). Find out how long a size 17 is in centimetres. How much bigger is his foot than yours?

10. As a class measure and record all students' foot lengths and prepare a graph depicting this. Then indicate Ian Thorpe's foot size against all members of the class. What is the average (mode, median and mean) class foot size?

11. What reasons can think of that make Ian Thorpe a faster swimmer than his competitors when he weighs 100 kilos, which is some 10 kilos heavier than Grant Hackett and Alex Popov and 19 kilos heavier than Michael Klim?

12. Ian Thorpe can swim the 200 metres in 1 minute, 44 seconds and 69 hundredths of a second. Using this time how long would it take him to swim 1 kilometre.Is it possible to estimate and then calculate how fast he swims using this time, in kilometres per hour. How would you calculate this? Have members of the class run 200 metres in the same time that it takes Ian Thorpe to swim 200 metres. Get them to note their observations.

13. If his average stroke frequency is 40.3 per minute how many strokes does he take to swim the 200 metres in the abovementioned time? (Be careful we are dealing with minutes, seconds and hundredths of seconds)
