The speed ratio of turbines refers to the ratio of the rotational speed of the turbine rotor to the rotational speed of the turbine shaft. This ratio is important for defining the mechanical performance and efficiency of the turbine.
ratio
The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
swirl ratio = air rotational speed / crank shaft speed of an ic engine
The speed ratio is typically calculated by dividing the speed of the input gear by the speed of the output gear in a gear system. This helps determine how much the output gear rotates in relation to the input gear in a given amount of time.
The ratio of 256km in 4h is speed. Speed = 256km/4h = 64km/h
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".

speed is the ratio of the distance an object moves per time unit (seconds,minutes hours)
SPEED
Yes it is. It is a rate of speed.
