You can put this solution on YOUR website!
Let x = walking speed
\n" ); document.write( "so 3x = running seed
\n" ); document.write( "Use \"distance+=+speed%2Atime\"\r
\n" ); document.write( "\n" ); document.write( "Equation: 3x + 2(3x) = 36
\n" ); document.write( " 9x = 36
\n" ); document.write( " x = 4
\n" ); document.write( "speed of walking = 4kph\r
\n" ); document.write( "\n" ); document.write( "Answer: 4 kph
\n" ); document.write( "
