Final answer:
The San Andreas Fault moves an average of 1,930 cm per year
Step-by-step explanation:
The San Andreas Fault has moved a total distance of 560 km over a period of approximately 29 million years. To determine the average distance it moves per year, we divide the total distance by the number of years.
560 km / 29 million years = 0.0193 km (or 19.3 meters) per year.
Since there are 100 cm in a meter, we can convert the distance to centimeters:
0.0193 km * 100,000 cm/km = 1,930 cm per year.
