GO GOLDEN GOPHERS!

The graph below describes the distance two cars have traveled after leaving a football game at the University of Minnesota.

1. Which car was traveling faster? How can you tell?

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

Car B was traveling faster.

Its line is steeper.

2. The lines cross at (2, 80). What does this point represent?

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

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

3. Assuming that Car A continued to travel at a constant rate, how far did Car A travel in the first 4 hours?

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?
