Final answer:
The correct answer is: a) 0.6 km. The explosion seen 600 meters away converts to 0.6 kilometers, as 1 kilometer is equal to 1,000 meters.
Step-by-step explanation:
The explosion was seen 600 meters north of the observation post. To convert meters to kilometers, we need to remember that 1 kilometer is equal to 1,000 meters. So, if the explosion was seen 600 meters away, we divide 600 by 1,000 to find the distance in kilometers.
600 meters ÷ 1,000 = 0.6 kilometers
This is the distance from the observation post to where the explosion was seen, providing us with the fact that explosions, distances, and conversions are critical in understanding real-world applications of mathematics.To find the distance of the explosion, we need to convert the given distance in meters to kilometers. Since there are 1000 meters in a kilometer, we divide 600 meters by 1000 to get 0.6 kilometers.
