The distance versus time graph for Object A and Object B are shown. *A graph titles Distance vs Time. A curved line is drawn through point 10 on y axis and this line is labeled Object A. The graph for Object B is shaped like a step passing through the origin* Which object moves with changing speed? A. Only Object B, because the graph has straight lines B. Only Object A, because the graph starts from the origin C. Both Object A and Object B, because the slope of the graph is the same throughout D. Both Object A and Object B, because different distances are traveled in the same time interval
