Question

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.

How many times did the submarine descend 50 meters?

Answer 1

To dive from 500 meters to 1,000 meters, the submarine needs to descend another 500 meters in total because 1,000 minus 500 equals <<1000-500=500>>500
The submarine needs to descend 10 times because 500 divided by 50 equals <<500/50=10>>10. Answer: \boxed{10}.

Answer 2

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.

How long did it take for the submarine to reach the depth of 1,000 meters?

Answer 3

The submarine descends 50 meters every 3 minutes, so to descend 500 meters it will take 3 minutes x 10 = <<3*10=30>>30 minutes.

Therefore, it took the submarine 30 minutes to reach the depth of 1,000 meters.

Answer: \boxed{30 \text{ minutes}}.
