walk rate = x mph
\n" ); document.write( "cycling rate = x+10 mph\r
\n" ); document.write( "\n" ); document.write( "walking distance = 8 miles
\n" ); document.write( "cycling distance = 28 miles
\n" ); document.write( "..
\n" ); document.write( "t= d/r
\n" ); document.write( "..
\n" ); document.write( "time riding = time walking\r
\n" ); document.write( "\n" ); document.write( "8/x=28/(x+10)
\n" ); document.write( "cross multiply\r
\n" ); document.write( "\n" ); document.write( "8(x+10)=28x
\n" ); document.write( "8x+80=28x
\n" ); document.write( "28x-8x=80
\n" ); document.write( "20x=80
\n" ); document.write( "/20
\n" ); document.write( "x= 4 walking rate
\n" ); document.write( "cycling rate = 4+10 =14 mph
\n" ); document.write( "
\n" ); document.write( "
