Answer:
The vertical distance between Dan and Jeff is of 26 feet.
Explanation:
Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake.
His position is -34 feet.
His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet.
Dives to 40 feet, and descends 20 more feet. So
-(40 + 20) = -60
What is the vertical distance between Dan and Jeff?
|-34 - (-60)| = |-34 + 60| = 26
The vertical distance between Dan and Jeff is of 26 feet.
