Well I guess we have to count how many of each are in a kilometer.
\n" ); document.write( "From a GOOGLE search, I found the following information,
\n" ); document.write( "dime:1.35 mm thickness
\n" ); document.write( "quarter:1.75 mm thickness
\n" ); document.write( "Let's assume it's correct.
\n" ); document.write( "So 1 km, which equals (1000)(1000)mm, there are this many dimes,
\n" ); document.write( "\"N%5Bd%5D=%281000%29%281000%29%2F%281.35%29=740741\"
\n" ); document.write( "Each dime is $0.10, so the total in 1 km is,
\n" ); document.write( "\"T%5Bd%5D=0.10%28740741%29=74074.10\"
\n" ); document.write( "Similarly for the quarters,
\n" ); document.write( "\"N%5Bq%5D=%281000%29%281000%29%2F%281.75%29=571429\"
\n" ); document.write( "Fewer of them, but what about the total value,
\n" ); document.write( "\"T%5Bq%5D=0.25%28571429%29=142857\"
\n" ); document.write( "Wow, it's almost double.
\n" ); document.write( "The exact difference is
\n" ); document.write( "\"T=T%5Bq%5D-T%5Bd%5D=142857-74074=68783\"
\n" ); document.write( "$68,783 difference between the two coin kilometers.
\n" ); document.write( "That's a lot of coin wrappers!
\n" ); document.write( "
\n" );
