Two cars started at the same position and were driven through a city using different streets. the red car traveled north 2 miles, then east 4 miles, and then south 6 miles. the green car traveled south 4 miles and then east 4 miles. both cars ended at the same location.

The red car traveled north 2 miles, then east 4 miles, and then south 6 miles. If we draw the total distance of the car in a cartesian plane, we end up in Quadrant IV, point (4, -4).

The green car traveled south 4 miles and then east 4 miles. In cartesian plane, we end up in Quadrant IV, point (4,-4).

It proved that both car ended up at the same location.
