Miles and kilometers are twi different scales for measuring distances. A 5-kilometer race is approximately 3.1 miles, and a 10-k

sveta [45]

Answer:

$x=\dfrac{y}{0.62}$

Step-by-step explanation:

$5\ \text{km}=3.1\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{3.1}{5}=0.62\ \text{miles}$

$10\ \text{km}=6.2\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{6.2}{10}=0.62\ \text{miles}$

Let $y$ be the distance in miles. So distance in km is given by

$x=\dfrac{y}{0.62}$ .

The equation that shows the approximate distance in kilometers as a function if the distance in miles is $x=\dfrac{y}{0.62}$ .
