Answer:
After 25 seconds, the equipment elevator will have descended 25 * 7 = 175 feet.
After 14 more seconds, the equipment elevator will have descended 175 + 14 * 7 = 217 feet.
The miners' elevator will have descended 25 * 16 = 400 feet after 14 seconds.
So, after 14 seconds, the miners' elevator will be 400 - 217 = 183 feet deeper than the equipment elevator.
