Answer:
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.
