Answer:
The answers to the given question are:
i. The equipment elevator is at a depth of 176 feet (-176 feet), while the miner's elevator is at a depth of 210 feet (-210 feet) below the surface.
ii. The miner's elevator is deeper than that of the equipment.
The speed of an object is the rate at which the object moves.
i.e. speed =
Thus,
Speed of the equipment elevator = 4 feet per second
Speed of the miner's elevator = 15 feet per second.
Time of descent of the equipment elevator = 30 + 14
= 44 seconds
So that, the distance of the elevator at this time is;
speed =
⇒ distance = speed x time
= 4 x 44
= 176
distance = - 176 feet
The distance of the miner's elevator after 14 seconds is:
speed =
⇒ distance = speed x time
= 15 x 14
= 210
distance = - 210 feet
Thus, after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miner's elevator is at a depth of 210 feet (-210 feet) below the surface.
Therefore, the miner's elevator is deeper than that of the equipment.
