Solve the problem.Rachel's bus leaves at 2:20 PM and accelerates at the rate of 3 meters per second per second. Rachel, who can run 7 meters per second, arrives at the bus station 3 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?
A. Bus: x1 = 
t2, y1 = 1; Rachel: x2 = 7(t - 3), y2 = 3
Rachel won't catch the bus.
B. Bus: x1 = 3t2, y1 = 1; Rachel: x2 = 
(t - 3), y2 = 3
Rachel will catch the bus at 2:24 PM
C. Bus: x1 = 
t2, y1 = 1; Rachel: x2 = 7(t + 3), y2 = 3
Rachel won't catch the bus.
D. Bus: x1 = t2, y1 = 1; Rachel: x2 = 7(t - 3), y2 = 3
Rachel will catch the bus at 2:25 PM
