As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written: y = k x.1. Proportional Relationships: The Basics. First, we must revisit the concept of proportional relationships. As you may recall, a proportional relationship exists when the ratio of two variables is constant. For instance, if you earn \($10\) for every hour you work, then your earnings and hours worked have a proportional relationship. 2.The calculator uses cross multiplication to convert proportions into equations which are then solved using ordinary equation solving methods. Be sure to enter something in each input box before clicking solve. Use the following as a guide: Variables. Any lowercase letter may be used as a variable.
