Answer

2 \, \text{cm/year} Explanation 1. Convert meters to centimeters 200 \, \text{m} = 200 \times 100 = 20,000 \, \text{cm} 2. Calculate rate in cm/year Rate = \frac{20,000 \, \text{cm}}{10,000 \, \text{years}} = 2 \, \text{cm/year}

Explanation

1. Convert meters to centimeters<br /> $200 \, \text{m} = 200 \times 100 = 20,000 \, \text{cm}$<br />2. Calculate rate in cm/year<br /> Rate = $\frac{20,000 \, \text{cm}}{10,000 \, \text{years}} = 2 \, \text{cm/year}$
