To convert a speed of 0.200 cm per second to units of kilometers per year, we need to perform a multi-step conversion. Here's the breakdown of the conversion:
1 centimeter (cm) = 0.00001 kilometers (km) 1 second (s) = 31536000 seconds per year (s/yr)
First, we'll convert 0.200 cm per second to kilometers per second: 0.200 cm/s * 0.00001 km/cm = 0.000002 km/s
Next, we'll convert kilometers per second to kilometers per year: 0.000002 km/s * 31536000 s/yr = 0.063072 km/yr
Therefore, a speed of 0.200 cm per second is equivalent to approximately 0.063072 kilometers per year.
