Speed in everyday life – basic principles
How it works
Speed describes how quickly an object moves. It indicates which distance is covered in a certain time. The common unit is meters per second (m/s) or kilometers per hour (km/h). Speed can be calculated by dividing the distance covered by the time needed. In everyday life, we encounter speed, for example, when walking, cycling, or driving a car. Speed can remain constant or change (acceleration or deceleration).
Note
To calculate the speed, divide the distance covered by the time needed for it: Speed = distance / time.
To calculate the speed, divide the distance covered by the time needed for it: Speed = distance / time.
An example
A car travels 120 kilometers in 2 hours. How great is the average speed in km/h?
The car travels 120 km in 2 h. Speed = 120 km / 2 h = 60 km/h. The average speed is 60 km/h.
