Define a function convert$\_$to$\_$kilometers$()$ that has two parameters as the number of miles and yards. The function returns the length converted to kilometers, given that:

$1$ yard $=0\mathrm{.}0009144$ kilometers

$1$ mile $=1760$ yards

Ex: If the input is:

$1$

$+273$

then the output is: :

$1\mathrm{.}859$ kilometers $*$

$1$ KILOMETERS$\_$PER$\_$YARD $=0\mathrm{.}0009144$

$2$ YARDS$\_$PER$\_$MILE $=1760$

$3$ def convert$\_$to$\_$kilometers$($num$\_$miles, num$\_$yards$)$:

$4$ return num$\_$yards$1760$

$5$

num$\_$miles $={\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(input())$

num$\_$yards $={\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(input())$

# Print with value rounded to $3$ decimal places
