The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below: Car A:
y = 52x + 70

Car B:
y = 54x + 56

After how many hours will the two cars be at the same distance from their starting point and what will that distance be?

6 hours, 420 miles
6 hours, 434 miles
7 hours, 420 miles
7 hours, 434 miles
