Final answer:
To convert 0.3 kilometers to meters, you multiply by 1000, getting 300 meters. This is compared with 500 meters to determine that 500 meters is the larger distance.
Step-by-step explanation:
The student's question involves converting distances between different units of measurement. Specifically, they have given a distance in kilometers and are asking to compare it to a distance in meters to determine the simplest form. To solve this, we need to use the basic conversion where 1 kilometer equals 1000 meters.
To convert 0.3 kilometers to meters, we multiply by 1000 (0.3 km x 1000 = 300 m). Therefore, 0.3 kilometers is equal to 300 meters, which is less than 500 meters. If we compare 0.3 km and 500 m, we can state that 500 m is the greater distance. There is no simpler form for a comparison, but for conversion purposes, it's vital to understand that the comparison is between 300 meters and 500 meters.
