Solve the problem.

Car A (travelling north at 30 mph) and car B (traveling west at 70 mph) are heading toward the same intersection. Car A is 3 miles from the intersection when car B is 4 miles from the intersection. Find parametric equations that describe the motion of cars A and B.



◦ Car A: x = 0, y = 30t - 3;  Car B: x = 4 - 70t, y = 0
◦ Car A: x = 0, y = 70t - 4;  Car B: x = 30t - 3, y = 0
◦ Car A: x = 70t - 4, y = 0;  Car B:  x = 0, y = 3 - 30t
◦ Car A: x = -30t + 3, y = 0;  Car B: x = 4 - 70t, y = 0
