Assignment 9-6-06

Using Dude Animation:

1) Make a table to keep track of Dude’s total distance traveled at various moments during the 12 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) Dude walked. If he changed speeds during the 12 seconds, then find all the speeds he walks and the intervals he walks at those speeds.

Starting at	Ending at	Dude walked at
______ 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 Dude had traveled in x seconds, 0 ≤ x ≤ 12. Be sure to say over what time interval each expression applies.

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