Final answer:
500 kilometers is equal to 500,000,000 millimeters, obtained by using the conversion factors of 1 km = 1000 m and 1 m = 1000 mm and multiplying them with 500.
Step-by-step explanation:
To convert 500 kilometers to millimeters, we need to understand the metric conversion factors. Each kilometer is equal to 1,000,000 millimeters since one kilometer equals 1,000 meters, and one meter equals 1,000 millimeters:
- 1 km = 1000 m
- 1 m = 1000 mm
Using these conversion factors, we multiply:
500 km x 1000 m/km x 1000 mm/m = 500,000,000 mm
Therefore, 500 kilometers is equal to 500,000,000 millimeters.
