Inverse proportionality is a mathematical relationship where one quantity increases while the other decreases. This means that if you double one value, the other value is halved. For example, if you consider the relationship between speed and travel time, as speed increases, the time taken to cover a distance decreases. In practical terms, if a car travels at a faster speed, it will take less time to reach its destination. This concept can be applied in various fields, such as physics, economics, and everyday life, helping to understand how different factors interact with each other, like distance, time, and speed.
