To find the number of times the submarine descended 50 meters, we can divide the difference in depth (1,000 meters - 500 meters = 500 meters) by the descent rate (50 meters).
500 meters / 50 meters = 10 times
Therefore, the submarine descended 50 meters 10 times.
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.

To find the time it took for the submarine to reach a depth of 1,000 meters, we need to divide the total distance traveled (1,000 meters - 500 meters = 500 meters) by the descent rate (50 meters) per 3 minutes.
500 meters / 50 meters = 10 dives
Each dive takes 3 minutes, so the total time taken is 10 dives * 3 minutes = 30 minutes.
Therefore, it took the submarine 30 minutes to reach a depth of 1,000 meters.
500 meters / 50 meters = 10 dives
Each dive takes 3 minutes, so the total time taken is 10 dives * 3 minutes = 30 minutes.
Therefore, it took the submarine 30 minutes to reach a depth of 1,000 meters.
