Question

A speedboat travels from the dock to the first buoy a distance of 20 meters in 18 seconds. It began the trip at a speed of 0 meters per second. By the time it reached the buoy, it was going 10 meters per second. What was the average velocity of the boat?

Answer 1

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.
