To calculate the average rate of movement of the Pacific Plate, you would typically need to know the distance it has moved over a specific period of time.
The formula to calculate the average rate of movement (R) is:
\[ R = \frac{D}{T} \]
where:
- \( D \) is the distance moved (in cm),
- \( T \) is the time period over which the movement occurred (in years).
For example, if the Pacific Plate has moved 2000 km (or 200,000,000 cm) over the past 5 million years, the average rate of movement would be:
\[ R = \frac{200,000,000 \text{ cm}}{5,000,000 \text{ years}} = 40 \text{ cm/yr} \]
If you can provide the specific distance and time period for the Pacific Plate's movement, I can help you calculate the average rate of movement accurately.
