You can add their speeds to get a
\n" ); document.write( "speed which is how fast they are
\n" ); document.write( "approaching eachother
\n" ); document.write( "Let Brenda's speed = $\"b\"$
\n" ); document.write( "Combined speed = $\"4.5+%2B+b\"$
\n" ); document.write( " $\"19.5+=+%284.5+%2B+b%29%2A3\"$
\n" ); document.write( " $\"19.5+=+13.5+%2B+3b\"$
\n" ); document.write( " $\"3b+=+6\"$
\n" ); document.write( " $\"b+=+2\"$
\n" ); document.write( "Brenda's speed is 2 km/hr\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
