\n" ); document.write( "----------
\n" ); document.write( "12 mins = 1/5 hours
\n" ); document.write( "d = r*t
\n" ); document.write( "r = d/t = 2 mi/(0.2) hr
\n" ); document.write( "r = 10 mi/hr
\n" ); document.write( "============
\n" ); document.write( "Or,
\n" ); document.write( "r = 2/12 mi/min * 60 min/hr = 120/12 mi/hr (notice how the units cancel if you do it right)
\n" ); document.write( "= 10 mi/hr
\n" ); document.write( "Whichever you prefer
\n" ); document.write( "
