Assignment 9-6-06

Using Clown Animation:

1) Make a table to keep track of Clown’s total distance during the 11 seconds that he walks.

Elapsed Time (sec)

Total Distance (ft)

Elapsed Time (sec)

Total Distance (ft)

2) Using the table, determine approximately how fast (ft/sec) Clown walked. If he changed speeds during the 11 seconds, then find all the speeds he walks and the intervals he walks at those speeds.

Starting at	Ending at	Clown walked at
______ sec	______ sec	______ ft/sec
______ sec	______ sec	______ ft/sec
______ sec	______ sec	______ ft/sec
______ sec	______ sec	______ ft/sec

3) Using the speeds you determined in part 2, write expressions that represent how far Clown had traveled in x seconds, 0 ≤ x ≤ 11. Be sure to say over what time interval each expression applies.

When x is greater than	But less than	This expression represents how far Clown had walked in x seconds
