Solve the problem.Rachel's bus leaves at 6:15 PM and accelerates at the rate of 3 meters per second per second. Rachel, who can run 6 meters per second, arrives at the bus station 6 seconds after the bus has left. Find parametric equations that describe the motions of the bus and Rachel as a function of time, and simulate the motion of the bus and Rachel by simultaneously graphing these equations.
A. Bus: x1 = 3t2, y1 = 1;
Rachel: x2 = 1(t - 6), y2 = 3
B. Bus: x1 = 
t2, y1 = 1;
Rachel: x2 = 6(t - 6), y2 = 3
C. Bus: x1 = 
t2, y1 = 1;
Rachel: x2 = 6(t + 6), y2 = 3
D. Bus: x1 = 3t2, y1 = 1;
Rachel: x2 = 6(t - 6), y2 = 3
