Question

Miles and kilometers are twi different scales for measuring distances. A 5-kilometer race is approximately 3.1 miles, and a 10-kilometer race id approximately 6.2 miles. Write an equation that shows the approximate distance in kilometers as a function if the distance in miles

Answer 1

`x=(y)/(0.62)`

Explanation:

`5\ \text{km}=3.1\ \text{miles}\\\Rightarrow 1\ \text{km}=(3.1)/(5)=0.62\ \text{miles}`

`10\ \text{km}=6.2\ \text{miles}\\\Rightarrow 1\ \text{km}=(6.2)/(10)=0.62\ \text{miles}`

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

`x=(y)/(0.62)`.

The equation that shows the approximate distance in kilometers as a function if the distance in miles is
`x=(y)/(0.62)`.
