Question

Suppose we represent the position above
the ground by a positive integer and that
below the ground by a negative integer.
An elevator descends into a coal mine
shaft at the rate of 10 m per minute.
What will be its position after 2 hour?​

Answer 1

Answer:

-1800

Step-by-step explanation:

elevator goes down at the rate of 10 meters

therefore:

position of elevator after 1 min:10 meters

position of elevator after 2 hrs:

[2hrs:180 mins]

-10x 180= -1800

hope it is correct.
