PLEASE HELP WITH MIDDLE SCHOOL MATH 1 Q THATS MULTIPLE CHOICE I NEED HELP PLEASE FOR BRAINLIEST*(08.06 MC)

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

All you have to do is try out both of the equations with each of the different choices.

200 = 45 (3) + 20
200 = 135 + 20
200 = 155

200 = 35 (3) + 60
200 = 105 + 60
200 = 165
So, this one does not work.
--------------------------------------------
180 = 45 (3) + 20
180 = 135 + 20
180 = 155

180 = 35 (3) + 60
180 = 105 + 60
180 = 165
So, this one does not work.
----------------------------------------------
200 = 45 (4) + 20
200 = 180 + 20
200 = 200

200 = 35 (4) + 60
200 = 140 + 60
200 = 200
So this one works.

The answer would be C.

I hope this helps and I'm sorry it took so long!

give them brainliest :3
