To calculate the average velocity, we use the formula:
Average velocity = Total displacement / Total time
In this case, the car moved 125 meters west in 3 hours. The total displacement is 125 meters to the west, and the total time is 3 hours.
Average velocity = 125 meters / 3 hours = 41.67 meters per hour to the west (rounded to two decimal places).
So, the car's average velocity to the west is approximately 41.67 meters per hour.
