A speedboat leaves the dock and travels 120m in 14 seconds. What is the average velocity of the speedboat in meters per second?

Average speed = (distance covered) / (time to cover the distance)

Average speed = (120 m) / (14 sec) = 8.57 m/s (rounded)

(about 19.2 mph)

Note:

That's the speedboat's average speed. We don't have

enough information to say anything about its velocity.
