A dolphin is at -- 28 feet. It swims up and jumps out of the water to a height of 8 feet. Find the vertical distance the dolphin
Helga [31]

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
