The distance-time graphs for two objects are shown below: (3 points) Two graphs labeled Object A and Object B are shown with distance in miles on y axis and time in hours on x-axis. The first graph is a curved line going up and passing through origin. The second graph is a straight line going up and passing through the origin Which statement is true? Both objects move at variable speeds. Both objects move at a constant speed. Object A is moving at constant speed but Object B is moving at variable speed. Object A is moving at variable speed but Object B is moving at constant speed.
