umm...why do you keep substituting different measurements into your equation. Why not just do ratios?

Which is bigger--mile or meter? mile, of course.
Hence, $\frac{mile}{meter}=\frac{1609}{1}$

In measurements, ratios are equal to 1,
an example: 1 mile = 1609 meters, therefore you write the ratio as $\frac{1mile}{1609meters}$ such as if I wanted to convert meters to miles I would do this...

$1609m_e=1609m_e$

$1609m_e\times1=1609m_e\times\frac{1m_i}{1609m_e}$

$1609m_e=\frac{1609m_im_e}{1609m_e}$

$1609m_e=\frac{<br /> \not{1609}m_i\not{m_e}}{\not{1609}<br /> \not{m_e}}$

$1609m_e=1m_i$

admitedly I can just substitute 1 mile for 1609 meters, but that is not what the way the person who asked this question wants.
