10 times

Answer 1

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.

Answer 3

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.
