Answer:
107 feet is the total vertical distance the dolphin traveled.
Step-by-step explanation:
Negative sign in front of the distance value is just to define the distance covered by dolphin underwater that is beneath the surface of the water
Before jump
Vertical distance covered by dolphin below the surface of water before coming out= 35 feet
Vertical distance covered by dolphin after coming out of the surface of water = 27 feet
After jump
Vertical distance covered by dolphin above the surface of water after jumping = 27 feet
Vertical distance covered by dolphin below the surface of water after jumping = 18 feet
The total vertical distance the dolphin traveled:
35 feet + 27 feet + 27 feet + 18 feet = 107 feet
