Aspeedboat 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.
