Final Answer:
The correct option is B) Equipment elevator: 115 feet, Miners elevator: 241 feet. Because equipment elevator is deeper.
Step-by-step explanation:
The key to solving this problem is to calculate the distance each elevator travels during the specified time intervals.
The equipment elevator descends for 23 seconds before the miners' elevator starts moving.
In these 23 seconds, the equipment elevator covers a distance of

Now, the miners' elevator begins descending 18 seconds after the equipment elevator, covering a distance of
during this time.
To find the final positions, add the distances covered by each elevator to their initial positions.
The equipment elevator is initially at the surface, so its final position is
The miners' elevator's initial position is also at the surface, so its final position is

Comparing the final positions, the equipment elevator is at 115 feet, and the miners' elevator is at 234 feet.
Therefore, the equipment elevator is deeper.
The correct answer is option B) Equipment elevator: 115 feet, Miners elevator: 241 feet. Because equipment elevator is deeper.
