Inverse variation: find the constant and missing values
The variables \(u\) and \(v\) have the following variation relationship
\[v \propto \frac{1}{u}\]
A known pair is \((1, 2.5)\) in the \((u,v)\) order
| u | \(1\) | \(10\) | \(50\) | ? |
|---|---|---|---|---|
| v | \(2.5\) | \(0.25\) | ? | \(\frac{1}{40}\) |
