Solve the problem.

Rachel's bus leaves at 2:40 PM and accelerates at the rate of 4 meters per second per second. Rachel, who can run 4 meters per second, arrives at the bus station 4 seconds after the bus has left. Find parametric equations that describe the motions of the bus and Rachel as a function of time. Determine algebraically whether Rachel will catch the bus. If so, when?
◦ Bus: x1 = 2t2, y1 = 1;  Rachel: x2 = 4(t - 4), y2 = 3
Rachel won't catch the bus.
◦ Bus: x1 = 4t2, y1 = 1;  Rachel: x2 = 2(t - 4), y2 = 3
Rachel will catch the bus at 2:44 PM
◦ Bus: x1 = 2t2, y1 = 1;  Rachel: x2 = 4(t + 4), y2 = 3
Rachel won't catch the bus.
◦ Bus: x1 = 2t2, y1 = 1;  Rachel: x2 = 4(t - 4), y2 = 3
Rachel will catch the bus at 2:45 PM
