Solve the problem.Car A (travelling north at 30 mph) and car B (traveling west at 20 mph) are heading toward the same intersection. Car A is 6 miles from the intersection when car B is 8 miles from the intersection. Find parametric equations that describe the motion of cars A and B. 
A. Car A: x = 0, y = 30t - 6; Car B: x = 8 - 20t, y = 0 B. Car A: x = 0, y = 20t - 8; Car B: x = 30t - 6, y = 0 C. Car A: x = -30t + 6, y = 0; Car B: x = 8 - 20t, y = 0 D. Car A: x = 20t - 8, y = 0; Car B: x = 0, y = 6 - 30t
