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 = 60x + 10
car b
y = 40x + 70
after how many hours will the two cars be at the same distance from their starting point and what will that distance be?
2 hours, 150 miles
2 hours, 190 miles
3 hours, 150 miles
3 hours, 190 miles
