Solve the problem.Rachel's bus leaves at 1:15 PM and accelerates at the rate of 3 meters per second per second. Rachel, who can run 8 meters per second, arrives at the bus station 5 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 = 
t2, y1 = 2;
Rachel: x2 = 8(t - 5), y2 = 4
B. Bus: x1 = 3t2, y1 = 2;
Rachel: x2 = 8(t - 5), y2 = 4
C. Bus: x1 = 
t2, y1 = 2;
Rachel: x2 = 8(t + 5), y2 = 4
D. Bus: x1 = 3t2, y1 = 2;
Rachel: x2 = 8(t - 5), y2 = 4
