Final answer:
To find the elevator's position after 35 minutes of descending at a rate of 4 meters per minute, multiply the rate by the time, resulting in a position 140 meters below the starting point.
Step-by-step explanation:
If an elevator descends into a mine shaft at the rate of 4 meters per minute, to determine its position after 35 minutes, we simply multiply the rate of descent by the time. The calculation would look like this:
- Rate of descent = 4 meters/minute
- Time = 35 minutes
- Position after 35 minutes = Rate of descent × Time
Therefore, the position after 35 minutes would be 4 meters/minute × 35 minutes = 140 meters.
This means the elevator will be 140 meters below its original starting point after 35 minutes.
