Answer:
The vertical depth travelled by the dolphin = 36 feet
Step-by-step explanation:
The dolphin is a fish that can jump out of the water and therefore it is used in circus shows and exhibitions.
Initially the dolphin is at a depth of 28 feet deep inside the water surface.It comes to water surface and then jumps out of the water to a height of 8 feet.
The vertical distance travelled by the dolphin can be found by taking the difference of final height and initial depth.
Vertical depth = final height - initial depth
= 8 - (-28)
= 36 feet
The vertical depth travelled by the dolphin = 36 feet
