How many kilometers does 3 centimeters represent on a map with a 1 to 10,000 scale?

Since the map has a 1 to 10,000 scale, 3 centimeters on the map would be 30,000 centimeters in reality.

We know that a centimeter is 1 one hundredth of a meter

So 30,000 centimeters is 300 meters.

One meter is 1 one thousandth of a kilometer, so 300 meters is 300 over 1000 kilometers

Which would be 0.3 kilometers.
