To find the distance that the submarine descended, we need to determine how many times it descended by 50 meters.
The depth of the submarine started at 500 meters, and it reached a depth of 1,000 meters. The difference between these depths is 1,000 - 500 = 500 meters.
Since the submarine descended by 50 meters every 3 minutes, we need to find how many times it descended by 50 meters in order to reach a depth of 500 meters.
To find this, we divide 500 by 50, which is 500 / 50 = 10.
Therefore, the submarine descended 10 times by 50 meters, resulting in a total distance of 10 * 50 = 500 meters.
Hence, the correct answer is 500 meters.
To find out the distance that the submarine descended, we need to calculate the total number of 50-meter descents it made.
Given that the submarine descends 50 meters every 3 minutes, we can divide the total depth (1,000 meters) by the descent rate (50 meters) to find the number of descents: 1,000 meters / 50 meters = 20.
Therefore, the submarine made 20 descents of 50 meters each. To find the total distance descended, we can multiply the number of descents (20) by the descent distance (50 meters): 20 descents * 50 meters/descent = 1,000 meters.
So, the distance that the submarine descended is 1,000 meters. The correct answer is "1,000 meters".
To find the total distance that the submarine descended, we need to find the sum of the distances descended in each interval.
The submarine descends 50 meters every 3 minutes until it reaches a depth of 1,000 meters. We can calculate the number of intervals by dividing the total depth change (1,000 meters - 500 meters = 500 meters) by the descent rate (50 meters).
Number of intervals = (Total depth change) / (Descent rate)
Number of intervals = (1,000 meters - 500 meters) / 50 meters
Number of intervals = 500 meters / 50 meters
Number of intervals = 10 intervals
Since each interval represents a descent of 50 meters, the total distance descended is given by:
Total distance descended = (Number of intervals) * (Descent rate)
Total distance descended = 10 intervals * 50 meters
Total distance descended = 500 meters
Therefore, the distance that the submarine descended is 500 meters, which is option D.
