You can put this solution on YOUR website!
his walking rate is 1/4 the distance every hour
\n" ); document.write( "his riding rate is the whole distance every hour
\n" ); document.write( "Let x=riding rate
\n" ); document.write( "let $\"x%2F4\"$ = walking rate
\n" ); document.write( "riding rate is 6kmh faster, so
\n" ); document.write( " $\"x=x%2F4%2B6\"$
\n" ); document.write( "Multiply through by 4 to clear the denominator:
\n" ); document.write( " $\"4x=x%2B24\"$
\n" ); document.write( "subtract x from both sides:
\n" ); document.write( " $\"3x=24\"$
\n" ); document.write( "divide both sides by 3:
\n" ); document.write( " $\"x=8\"$
\n" ); document.write( "so he rides at 8 km per hour
\n" ); document.write( " \n" ); document.write( "

\n" );
