Question

The city of Los Angeles is now approximately 2400 miles south of Alaska. It is moving slowly northward as the San Andreas fault slides along. If Los Angeles is to arrive near Anchorage, Alaska, in 76 million years, at what average rate will it have to move in mm per month?

Answer 1

The rate is

$$v=\frac{2400·1.609·1000·1000}{76,000,000·12}=4.23\text{ mm/year}.$$
