Answer:
The dolphins average speed is 3.51 
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?

distance=32,180 meters
- If 1 minute is equal to 60 seconds, 153 minutes is equal to how many seconds?

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:

So in this case the velocity is calculated as:

Solving, you get:
Speed= 3.51 
<u><em>The dolphins average speed is 3.51 </em></u>
