The correct answer is: velocity, but neither acceleration nor speed.
To understand why, let's define these terms:
1. Velocity: Velocity is a vector quantity that describes both the speed and direction of an object's motion. In this case, the car is traveling west, so it has velocity.
2. Speed: Speed is a scalar quantity that only describes how fast an object is moving. It does not take into account the direction of motion. Although the question mentions a constant rate, it does not specify the speed. Therefore, we cannot determine the speed of the car from the given information.
3. Acceleration: Acceleration is the rate at which an object's velocity changes over time. Since the question states that the car is traveling at a constant rate, it means the velocity is not changing. Hence, there is no acceleration.
So, in summary, the car has velocity (westward), but we cannot determine the speed or acceleration based on the given information.
