1. Understand Velocity

Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.

* Magnitude: How fast something is moving (in this case, meters per second).

* Direction: The way the object is moving (e.g., west, east, north, south).

2. Calculate Displacement

* Ben starts 3 meters west of Main Street.

* He ends up 45 meters west of Main Street.

* His displacement is 45 meters - 3 meters = 42 meters west.

3. Calculate Velocity

* Velocity = Displacement / Time

* Velocity = 42 meters west / 6 seconds

* Velocity = 7 meters per second west

Answer: Ben's velocity is 7 meters per second west.
