Final answer:
Kilometers are used to measure long distances, with one kilometer equaling 1,000 meters. Meters are used for shorter distances. To convert from meters to kilometers, divide by 1,000.
Step-by-step explanation:
The appropriate unit of measure to use when measuring long distances such as a track or the distance around a block would be kilometers. Kilometers are the longest unit of metric measurement, commonly abbreviated as 'km'. One kilometer is equivalent to 1,000 meters, making it a substantially larger unit than meters which are used for shorter distances like the lengths of houses or pools. For instance, converting meters to kilometers is a simple process where one divides the number of meters by 1,000.
To convert 80 meters to kilometers, you apply the conversion factor that 1 km equals 1,000 m. Therefore, 80 m would be converted to kilometers by dividing 80 by 1,000, which equals 0.08 kilometers. It is essential to choose the correct unit of measurement to accurately represent the distance being measured.
