Answer:
Definition of Speed: Speed is defined as the rate at which an object covers a distance. It is the distance travelled per unit time.
Calculation using v = s/t:
The equation v = s/t states that speed (v) is equal to the distance (s) travelled divided by the time (t) taken to travel that distance. This means that to calculate speed, you need to know how far an object has travelled and how long it took to travel that distance. You then divide the distance by the time.
For example, if an object travels 100 metres in 5 seconds, its speed is 100m / 5s = 20 m/s.
