1. Using Distance and Time:
* Understanding the Formula: Speed is calculated by dividing the distance traveled by the time it took to cover that distance. This is represented by the formula: Speed = Distance / Time
* Gathering Information: You need to know how far the car traveled (distance) and how long it took to travel that distance (time).
* Applying the Formula: Plug the distance and time values into the formula. For example, if the car traveled 120 kilometers in 2 hours, its speed would be: 120 km / 2 hours = 60 km/h.
2. Using a Speedometer:
* Direct Measurement: The simplest way to determine a car's speed is by looking at its speedometer. This instrument directly measures and displays the car's speed in units like kilometers per hour (km/h) or miles per hour (mph).
Important Considerations:
* Units: Make sure the distance and time units are consistent (e.g., kilometers and hours).
* Average Speed: The calculations above give you the average speed over a specific distance and time. The car may have been traveling faster or slower at different points during the journey.
* Instantaneous Speed: To get the car's speed at a specific moment, you need a speedometer or similar device.
