Question

The distance from this place to the Mid-Atlantic Ridge, where the crust initially formed, is about 1920 miles. What is the average rate of motion for North American Plate in miles per million years

Answer 1

Answer: ‭0.00192‬ miles per million years

Step-by-step explanation:

The formula for speed is:

= Distance / Time

As no time has been given yet the question makes mention of miles per million years, I will assume that the time is a million years. In which case the average range of motion is:

= 1,920 / 1,000,000

= ‭0.00192‬ miles per million years
