Question:

A dolphin travels a distance 20 miles up the coastline in 153 minutes. If 1 mile is equal to 1609 meters, then what is the dolphins average speed in meters/seconds rounded to the nearest tenth?

Answers

The dolphins average speed is 3.51 [tex]\frac{meters}{seconds}[/tex]

Explanation:

First of all, the following rules of three should be applied:

If 1 mile is equal to 1609 meters, 20 miles are equal to how many meters?

[tex]distance=\frac{20 miles*1609 meters}{1 mile}[/tex]

distance=32,180 meters

If 1 minute is equal to 60 seconds, 153 minutes is equal to how many seconds?

[tex]time=\frac{153 minutes*60 seconds}{1 minute}[/tex]

time= 9,180 seconds

Speed ​​is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. That is, speed implies the change of position of an object in space within a certain amount of time and is calculated as:

[tex]speed=\frac{distance}{time}[/tex]

So in this case the velocity is calculated as:

[tex]speed=\frac{32,180 meters}{9,180 seconds}[/tex]

Solving, you get:

Speed= 3.51 [tex]\frac{meters}{seconds}[/tex]

The dolphins average speed is 3.51 [tex]\frac{meters}{seconds}[/tex]

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).
