The statement that includes a description of velocity is:
**A car travels east at 45 kilometers per hour.**
Velocity is defined as the speed of an object in a given direction, which this statement provides.
**A car travels east at 45 kilometers per hour.**

To determine if either object has a constant velocity, we analyze the definitions:
- **Constant velocity** means both the speed and the direction of movement remain unchanged.
1. **A car travels east at 45 kilometers per hour.** (constant speed and direction)
2. **A bicycle moves 8 meters per second.** (speed is constant, but direction is unspecified)
3. **A student walks 20 meters down the street.** (distance traveled is specified, but direction is not clear)
4. **A marble rolls 30 centimeters away from the table.** (this measures distance from a point but doesn't specify a direction or speed over time)
Based on this analysis:
- The car has a defined constant velocity since both speed and direction are given.
- The other objects lack sufficient information to specify a constant velocity.
Therefore, the correct response is:
**Only object A has a constant velocity.**
If "object A" was not listed, please refer to the correct object from your context. The overlapping responses indicate the necessity of context to respond accurately. If A was indeed referred to as traveling east with a constant speed, then that response holds valid.
