Answer
To find average velocity from a distance (x given in cm) versus time (t given in s) graph of a function, you must calculate the slope of the function over the given time period. (see attached image for calculations and graph)
To find the instantaneous velocity at a given time, you must find the slope of the tangent line to the function at that point (see attached image for calculations and graph)
