Answer 1

Answer:

here your answer ✨

Step-by-step explanation:

Since, we represent the distance above the ground by a positive integer and that below the ground by a negative integer, the elevator going down a mine shaft will have negative value. Hence, position of elevator after one hour is \(240 \;m\) below the ground level.
