The problem:
A ball is moving at 10 cm/s when clock time is 4 seconds, and at 40 cm/s when clock time is 9 seconds.
Sketch a v vs. t graph and represent these two events by the points (4 sec, 10 cm/s) and (9 s, 40 cm/s).
Sketch a straight line segment between these points.
What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
the rise is 30 and the run is 5. This gives a slope of 6.
@&
These quantities have units, but otherwise OK.

What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The area would be the distance covered by the object.
@&
You need to calculate the area of this trapezoid, including units.
You are correct that the area would be the distance covered.

@&
Not bad, but you need units, and you need to calculate that area.
Should take you only a couple of minutes.
