.\ Define the positive direction as forward, toward the center of the field and consider what a position versus time graph of her motion would look like. Rank the sprints according to their slopes on the position versus time graph, from steepest positive slope to steepest negative slope\ Rank from steepest positive slope to steepest negative slope. To rank items as equivalent, overlap them.
