A body is at rest at x=0. At t=0, it starts moving in the positive X direction with a constant acceleration. At the same instant another body passes through x=0 moving in the positive X direction with a constant speed. The position of the first body is given by x1t after time t and that of the second body by x2t after the same time interval. Which of the following graphs correctly describes x1-x2 as a function of time t?
