SI unit for speed
The SI unit for speed is meter per second (m/s).
Explanation
Speed is defined as the distance traveled by an object in a given time. It is a scalar quantity and is measured in units of distance per time. The SI unit of distance is meter (m) and the SI unit of time is second (s). Therefore, the SI unit of speed is meter per second (m/s).
For example, if a car travels a distance of 100 meters in 10 seconds, its speed can be calculated as:
Speed = Distance/Time
= 100 meters/10 seconds
= 10 meters per second (m/s)
Therefore, the speed of the car is 10 m/s.
Conclusion
In conclusion, the SI unit for speed is meter per second (m/s). It is important to use the correct units when measuring speed to ensure consistency and accuracy in calculations.

You know that speed=distance/time. and the si unit of distance=metre and the si unit of time =second. so, the si unit of speed=si unit of distance/ si unit of time=m/s.
