a plate moves 200 m in 10,000 years. what is its rate in cm/year? 0.02 cm/year 2 cm/year 10 cm/year 100 cm/year
Answer
Explanation:
Step1: Convert meters to centimeters
Since 1 m = 100 cm, 200 m is $200\times100 = 20000$ cm.
Step2: Calculate the rate
The rate is distance divided by time. So the rate is $\frac{20000\text{ cm}}{10000\text{ years}}= 2$ cm/year.
Answer:
2 cm/year
