The people from the testing center took it and said that you would pick it up.
@& Thanks. I should be able to pick the test up tomorrow.*@
What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
62.5cm/sec, the area of the trapezoid measuring 20cm/sec (v0-vf)/2 and 2.5sec (to-tf)/2.

@& Very good reasoning. You are seeing the displacement as the area of the trapezoid.
You did have a couple of errors in the details, though.
The average altitude of the trapezoid is the average of the two altitudes v0 and vf. The average altitude is therefore (v0 + vf) / 2, not (v0 - vf) / 2.
The width of the trapezoid is the change in the clock time, not half the change in the clock time.
Also note that cm / s * s = cm, not cm/s.*@
*#&!
@& You're definitely on the right track here, but you do need to make a couple of revisions.
