The kids ran 83 feet from the steps of Altgeld hall to the Alma Mater statue.  The kids ran the distance in the following times: 6 sec, 6 sec, 7 sec, 10 sec, 11 sec.  How do these times compare with certain animals:

A tortoise will travel the same distance in 56 seconds
A cheetah will travel the same distance in 1 second


Coordinates with graph paper

Re-affirm degree coordinate system.  




Homework answer - Calculate the corresponding degrees of the southwest direction and the northwest direction.
Southwest - 225
Northwest - 315

At defined starting point on graph paper, draw lines using the following direction.

0 deg - 3 spaces
90 deg - 10 spaces
180 deg - 3 spaces
270 deg - 10 spaces

0 deg - 3 spaces
90 deg -2 spaces
45 deg - 2 spaces
90 deg - 2 spaces
135 deg - 2 spaces

What did you make if you add wheels to the bottom?
