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.

Answer 1

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.
