By using speed time and distance formulas we can easily find the three values. Formula for Speed Speed refers to distance traveled during a period of time. The triangles will help you remember these three rules.
To work out what the units are for speed you need to know the units for distance and time.
Distance Speed x Time. Speed is measured as the ratio between the distance and time and the SI unit of speed is ms. The formula for finding the instantaneous speed at a specific point is found by taking the derivative of the speed equation. What is the d in the speed formula.
