A mine worker is in a tunnel 25 feet below the ground. He descends another 13 feet. What is his final position?

38 feet below the ground.

Step-by-step explanation:

A mine worker is in a tunnel. His position below the ground = 25 feet

He descends another 13 feet.

He is below the ground and he again descends another 13 feet.

Therefore we have to put the values in negative.

(-25) + (-13)

= - 38 feet.

His final position is 38 feet below the ground.

-38

Step-by-step explanation:

-25 + - 13 = - 38

The worker is 25 feet underground and continues to go deeper so your answer will be in the negatives.
