A submarine is diving at a depth of 500 meters. Every 3 minutes, it descends another 50 meters. It then reaches a depth of 1,000 meters.
What is the distance that the submarine descended?

To find the distance that the submarine descended, we need to calculate the total number of 50-meter descents it made.
The submarine descends another 50 meters every 3 minutes, so in every 3-minute interval, it descends 50 meters.
The descent from 500 meters to 1,000 meters is a total of 1,000 - 500 = <<1000-500=500>>500 meters.
Since the submarine descends another 50 meters every 3 minutes, the total number of 50-meter descents it made is 500 / 50 = <<500/50=10>>10.
Therefore, the distance that the submarine descended is 10 * 50 = <<10*50=500>>500 meters.
So the correct answer is 500 meters.
The submarine descends 250 meters.
To find the distance that the submarine descended, we need to calculate the total change in depth.
The submarine initially starts at a depth of 500 meters and descends every 3 minutes by 50 meters. We can calculate the number of times the submarine descends by dividing the change in depth (500 meters) by the amount it descends each time (50 meters).
Number of descents = change in depth / descent rate
Number of descents = 500 meters / 50 meters = 10 descents
Next, we need to determine the total distance descended by multiplying the number of descents by the descent rate (50 meters):
Total distance descended = number of descents * descent rate
Total distance descended = 10 descents * 50 meters = 500 meters
Therefore, the submarine has descended a total distance of 500 meters.
