Which speed is the one that refers to a precise instant?
Speed
Explanation
The **instantaneous speed** is the one that refers to a specific moment in time. It is the speed that a vehicle has at a precise instant, like when you look at a car's speedometer and see the exact speed at that moment.
- **Average speed** refers to the average speed over an entire journey, not at a specific instant.
- **Excessive speed** is when a vehicle exceeds the allowed speed limit, but it also does not refer to a precise instant.
Therefore, the speed that refers to a precise instant is the **instantaneous speed**.
