Question

Suppose we represent the distance below the ground by a negative integer and that above the ground by a positive integer, then what will be the position of an elevator after 57 minutes, if it starts 17 meters above the ground to descends into a mine shaft at the rate of 4 meter per minute? * 2 points​

Answer 1

Answer:

answer is : Since, the elevator going down, so the distance covered by it will be represented by a negative integer.

Change in position of elevator in one minute = −5 m.

Position of the elevator after 60 minutes = (−5)×60=−300 m

That means the position of the elevator will be 300 m below ground level.
