Two quantities are said to be

In other words, two quantities are inversely proportional if the

*inversely proportional*if their measurements evolve in opposite direction.In other words, two quantities are inversely proportional if the

**product**of their quantities is a constant number.### Example

To travel a certain given distance \(d\), the speed \(v\) and the time \(t\) are two inversely proportional quantities connected in the relationship \(d = vt\). The faster the vehicle goes, the less time it will take to travel the same distance. Therefore, the quantities \(v\) and \(t\) vary in opposite directions.
