Distance input
--------------- = Speed Ratio
Distance output
The distance input divided by the distance output equals the Speed Ratio.
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.
The speed of an object at a time is found by determining its rate of change of distance. If the speed is constant, it can be determined by the ratio of distance to time taken.
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
The ratio of distance moved to the time taken to move that distance is the speed of the object. Speed is a measure of how quickly an object changes its position. Mathematically, speed = distance/time.
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.

The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
The speed of an object at a time is found by determining its rate of change of distance. If the speed is constant, it can be determined by the ratio of distance to time taken.
swirl ratio = air rotational speed / crank shaft speed of an ic engine
The ratio of 256km in 4h is speed. Speed = 256km/4h = 64km/h
Distance and time.
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
Yes it is. It is a rate of speed.
speed is the ratio of the distance an object moves per time unit (seconds,minutes hours)
