According to the given data we have the following:
a worker in a sliver mind descends 42ft into a mine shaft
To write this as an integer, first you should look for key words. The word “descends” means the integer will be negative.
So, if we suppose that he would descends 42 ft, we suppose that the 42 ft would be underground.
Therefore, if he descends 42 ft from the ground, the integer that represents the change in the workers position would be -42 ft.
So, the integer that represents the change in position is -42 ft
