Convert mi/hr to in/min
\n" ); document.write( "[ 55 mi/hr ] x [ 1/60 hr/mins ] x [ 5280 ft/mi ] x [ 12 in/ft ]
\n" ); document.write( "\"+55%2A%28+1%2F60+%29%2A5280%2A12+=+58080+\" in/min
\n" ); document.write( "---------------------------
\n" ); document.write( "How many times does the circumference, C, of the
\n" ); document.write( "wheel go into this number?
\n" ); document.write( "\"+C+=+2%2Api%2A30+\"
\n" ); document.write( "\"+C+=+60%2Api+\"
