Answer:

  • equipment: -252 feet; miners: -224 feet
  • equipment is deeper

Step-by-step explanation:

The attached graph shows the depth of the elevators with respect to the time the miners' elevator started.

After 14 more seconds, the positions are ...

  equipment: -6(42) = -252 feet relative to the surface

  miners: -16(14) = -224 feet relative to the surface

The equipment elevator is deeper.
