Question

there are about 1.61 kilometers in 1 mile. let x represent a distance measured in kilometers and let y represent the same distance measured in miles. complete the equations that relate a distance measured in kilometers and the same distance measured in miles. write each answer as a decimal to the nearest hundredth. x = y y = x

Explanation:

Step1: Find the conversion from miles to kilometers

Given 1 mile = 1.61 kilometers. If $y$ is in miles and $x$ is in kilometers, then $x = 1.61y$.

Step2: Find the conversion from kilometers to miles

We know $x = 1.61y$, so $y=\frac{x}{1.61}\approx0.62x$.

Answer:

$x = 1.61y$
$y = 0.62x$
