does the slope of a distance vs. time graph show
the average velocity
or the
instaneous velocity
I'm asked the question and don't know which one. I believe that it would be the instaneous value because the slope is refering to one point on the graph... not sure though

physics 
drwls,
You are right. Slope is measured tangent to the positiontime curve. If the velocity is changing, there is only one tangent point. Slope of the tangent line is the instantaneous velocity

QUESTION 
QUESTION,
what if the velocity is kept constant
or is suppose to at least 
physics 
drwls,
If the velocity is constant (over a finite time interval) the average velocity during that interval and the instaneous velocity are the same.
