You can put this solution on YOUR website!
Actual wheel diameter: Model wheel diameter
\n" ); document.write( "33 inches : 3 inches
\n" ); document.write( "11 : 1
\n" ); document.write( "Therefore:
\n" ); document.write( "Actual length : Model length
\n" ); document.write( "240 inches : 21.81 inches
\n" ); document.write( "You are dividing the actual dimension
\n" ); document.write( "by 11, after you convert both to the same units
\n" ); document.write( "namely, inches.
\n" ); document.write( "Hope this helps.
