When you use a graph to solve a problem about how far a car traveled during a specified time during which it?

Question

was accelerating how many area calculations do you have to make?what is/are the shape you are calculating?

Answer 1

If you graph velocity as a function of time you calculate the area under the velocity curve.  If the acceleration is constant, the curve will be a parabola.  The number of area calculations you need to make depends on the accuracy you need, since you will be using rectangle or trapezoid approximations to the actual area.
