Final answer:
The Pacific plate will travel 50 kilometers in 1 million years.
Step-by-step explanation:
The Pacific plate is moving at a speed of 5 centimeters per year. To calculate how many kilometers it will travel in 1 million years, we can convert the speed from centimeters per year to kilometers per million years. There are 100,000 centimeters in a kilometer and 1 million years in a million years, so the plate will travel 5/100,000 kilometers per year. Multiply this by 1 million to get the total distance traveled in 1 million years:
5/100,000 * 1,000,000 = 50 kilometers
