Bill ran at 12 kilometers per hour while Leo ran at 10 kilometers per hour.
\n" ); document.write( "How long did it take for them to be 2/3 of a kilometer apart?
\n" ); document.write( ":
\n" ); document.write( "If x = their running time
\n" ); document.write( "We know bill's dist is 12x and Leo's dist is 10x, the dif is 2/3 km
\n" ); document.write( ":
\n" ); document.write( "12x - 10x = \"2%2F3\"
\n" ); document.write( "
\n" );
