3-8.

You can find this by discovering which car traveled a farther distance in a shorter amount of time.

Car B was traveling faster.

It's line is steeper.

What are the units for the *x* and *y* coordinates?

In 2 hours, both cars will be 80 miles from the game.

Because Car A traveled 80 miles in 2 hours at a constant rate, it went 40 miles in 1 hour.

If the Car A travels 40 miles every hour, how far will it travel in 4 hours?
