Concept of speed
Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed.
The units will be in metres per second (m/s) in this example since the distance is measured in metres (m) and the time is measured in seconds (s).
What is the formula for speed?
The formula for speed is as straightforward as dividing a distance by a time.
To calculate speed, divide the distance travelled (say, 3 metres) by the passing time (say, 3 seconds) (one metre per second).
So, the rate at which an object’s position changes in any direction can be defined as speed.
The speed formula is as follows: [Speed = Distance]
