and then we can combine them
so, we will have to change 3520 yards into miles
we know that
or we can also write it as
now, we can find for 1 yard
so, we can divide both sides by 1760
now, we can find for 3520 yards
so, we can multiply both sides by 3520
now, we can replace it in our expression
now, we can simplify it
