Answer 2

Answer:

It will take the elevator 10 minutes to reach the mine.

Step-by-step explanation:

To find the answer, we need to add the distance from the starting point (8mt above ground) with the destination (42mt below ground) assuming the mine shaft is travalling at the constant speed. 50mt/5 = 10minutes.
