Chapter 0.3, Problem 20E

To determine

To find: The distance of the dolphin below the oceans surface.

Answer to Problem 20E

  $42\text{ feet}$ .

Explanation of Solution

Given information:

A dolphin swims $24\text{ feet}$ below the ocean’s surface and then dives $18\text{ feet}$ straight down.

Formula used:

When a quantity is added to the existing quantity it’s called addition.

Calculation:

Consider the provided situation, a dolphin swims $24\text{ feet}$ below the ocean’s surface and then dives $18\text{ feet}$ straight down.

Initially dolphin is $24\text{ feet}$ below the ocean’s surface and it goes more $18\text{ feet}$ straight down.

That is dolphin is very deep down ocean’s surface.

The distance below the ocean’s surface where the dolphin is present is,

  $24+18=42$

Thus, the distance of the dolphin below the oceans surface is $42\text{ feet}$ .
