Answer:
The equipment elevator is positioned 481 feet closer and the miner equipment is positioned 342 feet closer relative to the surface. The equipment elevator is deeper.
Step-by-step explanation:
The rate that both elevators descend are the same according to the information given in the question.
After 18 seconds, the equipment elevator has descended 18 x 13 = 234 feet.
After another 19 seconds, the equipment elevator has descended for a total of 37 seconds which results in 481 feet and the miner elevator has descended for 19 seconds which gives us a descend of 342 feet.
So they are 481 and 342 feet closer relative to the surface and the equipment elevator is deeper since it has descended for a longer period of time.
I hope this answer helps.

➷ To find the mean you add together the values and divide by how many values there are:
150 + 100 + 120 + 200 + 180 + 300 + 250 = 1300
1300/7 = 185.714285
Median:
Order the values and find the middle one:
100, 120, 150, 180, 200, 250, 300
As you can see, it is 180
