Click on the measure that is equivalent to 3 kilometers. 30 meters 30,000 meters 3,000 meters 300 meters
The Correct Answer and Explanation is:
The correct answer is 3,000 meters.
To determine the correct conversion from kilometers to meters, it is essential to understand the metric system’s structure. The metric system is a decimal based system of measurement where units are related by powers of ten. The prefix “kilo” is a key part of this system, and it signifies a factor of one thousand (1,000).
Therefore, one kilometer is by definition equal to 1,000 meters. To find the equivalent of 3 kilometers in meters, you perform a simple multiplication. You take the number of kilometers, which in this case is 3, and multiply it by the conversion factor of 1,000 meters for every one kilometer.
The calculation is as follows:
3 kilometers × 1,000 meters/kilometer = 3,000 meters.
This result directly matches one of the provided options. Let’s analyze why the other choices are incorrect. The option “30 meters” represents a much shorter distance, only 0.03 kilometers. The value “300 meters” is also incorrect, as it is equivalent to 0.3 kilometers, which is ten times smaller than the target distance. A common mistake is selecting “30,000 meters,” but this value is ten times too large. Since 1,000 meters equal 1 kilometer, 30,000 meters would be equivalent to 30 kilometers, not 3. This error often arises from misplacing the decimal point or adding an extra zero during multiplication.
In summary, by remembering that the prefix “kilo” means one thousand, the conversion becomes a straightforward process of multiplying by 1,000. This leads to the correct answer that 3 kilometers is equivalent to 3,000 meters.
