Solve the problem.Car A (travelling north at 70 mph) and car B (traveling west at 60 mph) are heading toward the same intersection. Car A is 5 miles from the intersection when car B is 7 miles from the intersection. Find parametric equations that describe the motion of cars A and B. 
A. Car A: x = -70t + 5, y = 0; Car B: x = 7 - 60t, y = 0
B. Car A: x = 0, y = 60t - 7; Car B: x = 70t - 5, y = 0
C. Car A: x = 60t - 7, y = 0; Car B: x = 0, y = 5 - 70t
D. Car A: x = 0, y = 70t - 5; Car B: x = 7 - 60t, y = 0
