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. ExponentsThe equation for any proportional relationship looks like y=kx, where x and y represent the related quantities and k is the constant of proportionality. Some ...Write an equation that shows the relationship between the distance he runs, d, in kilometers and the time he spends running, h, in hours. So, pause this video and see if you can work through that on your own before we do it together. All right, now there's several ways to approach this question.Let's graph the equation y = 2.5x. For every increase of 1 in x, y increases by 2.5. We call this the "unit rate" or "slope". The graph shows a proportional relationship because y changes at a constant rate as x changes and because y is 0 when x is 0.

And when X is six, Y looks to be, 1 and 1/3 times X. So you don't have the same proportionality constant the entire time. So, we have zero proportional relationships depicted here. So I would pick zero there. Let's do one more example. Natalie is an expert archer.Solving proportional equations is fairly trivial, if you know the basic equation transformation laws - multiplying and dividing both sides by the same number is all that is required.
