Answer:
The average velocity of the boat during the trip from the dock to the first buoy is approximately 1.111 meters per second.
Step-by-step explanation:
To calculate the average velocity of the boat, we use the formula for average velocity:
Average velocity = Total displacement / Total time
In this scenario, the total displacement is the distance from the dock to the first buoy, which is 20 meters. The total time is the time taken to reach the buoy, which is 18 seconds.
Average velocity = 20 meters / 18 seconds
Now, let's calculate the average velocity:
Average velocity = 1.111... meters per second (rounded to three decimal places)
So, the average velocity of the boat during the trip from the dock to the first buoy is approximately 1.111 meters per second.
