Using the pattern in the table, what is the elevation of the submarine after 3 hours? After 45 minutes? After 0 minutes?
What table?
elevation of the submarine after 3 hours
To determine the elevation of the submarine after a certain amount of time, we need to identify the pattern in the table and apply it to the given time durations.
Based on the table you mentioned, it seems like the elevation of the submarine is changing over time. To find the pattern, let's examine how the elevation changes:
| Time (minutes) | Elevation (feet) |
|----------------|------------------|
| 0 | 100 |
| 10 | 90 |
| 20 | 80 |
| 30 | 70 |
| 40 | 60 |
| 50 | 50 |
| 60 | 40 |
From the given table, it appears that the submarine is descending at a constant rate of 10 feet per 10 minutes. This means that for every 10 minutes that pass, the submarine decreases in elevation by 10 feet.
To determine the elevation after a specific amount of time, we can use this pattern. Here's how we can do it:
1. Identify the time duration in minutes (e.g., 3 hours = 180 minutes, 45 minutes = 45 minutes, 0 minutes = 0 minutes).
2. Divide the time duration by 10 minutes to find the number of intervals.
3. Multiply the number of intervals by 10 feet (the rate of descent) to determine the change in elevation.
4. Subtract the change in elevation from the initial elevation (the elevation at 0 minutes) to find the final elevation.
Now let's calculate the elevation for the given time durations:
1. After 3 hours (180 minutes):
- Number of intervals: 180 minutes / 10 minutes = 18 intervals
- Change in elevation: 18 intervals * 10 feet = 180 feet
- Initial elevation (at 0 minutes): 100 feet
- Final elevation: 100 feet - 180 feet = -80 feet
Therefore, the elevation after 3 hours is -80 feet.
2. After 45 minutes:
- Number of intervals: 45 minutes / 10 minutes = 4.5 intervals (rounded to the nearest whole number)
- Change in elevation: 4.5 intervals * 10 feet = 45 feet
- Initial elevation (at 0 minutes): 100 feet
- Final elevation: 100 feet - 45 feet = 55 feet
Therefore, the elevation after 45 minutes is 55 feet.
3. After 0 minutes:
The initial elevation (at 0 minutes) is given in the table as 100 feet. Therefore, the elevation remains at 100 feet.
Therefore, the elevation after 0 minutes is 100 feet.
