Question

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 = 45x + 20

Car B
y = 35x + 60

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

3 hours, 200 miles
3 hours, 180 miles
4 hours, 200 miles
4 hours, 180 miles
