Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
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
Speed can be exoressed as a ratio
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".
3:31
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.
