Answer:
[tex]y=1.60934x[/tex]
Step-by-step explanation:
If x is directly proportional to y, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
We know that,
1 miles = 1.60934 km
It is given that x-miles and y- kilometers. Constant of proportionality is 1.60934.
[tex]y=1.60934x[/tex]
Hence, the required equation is [tex]y=1.60934x[/tex].
