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 + 15


Car B:

y = 46x + 63


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


8 hours, 510 miles

8 hours, 431 miles

7 hours, 510 miles

7 hours, 431 miles
