Average speed is a measure of how fast an object moves over a certain distance. It is calculated by dividing the total distance traveled by the total time taken. For example, if a car travels 100 kilometers in 2 hours, its average speed would be 50 kilometers per hour. This concept is important in various fields, including physics, engineering, and everyday life. Understanding average speed helps in planning trips, estimating travel times, and analyzing motion. It provides a simple way to compare the speeds of different objects or vehicles, making it easier to understand their performance.
