\n" ); document.write( "We can treat this as a \"shared work\" problem
\n" ); document.write( "Let the dist between the school and home = 1
\n" ); document.write( "Let t = time required for them to meet
\n" ); document.write( ":
\n" ); document.write( " $\"t%2F20\"$ + $\"t%2F10\"$ = 1
\n" ); document.write( "Multiply each term by 20
\n" ); document.write( "t + 2t = 20
\n" ); document.write( "3t = 20
\n" ); document.write( "t = $\"20%2F3\"$
\n" ); document.write( "t = 6 $\"2%2F3\"$ min or 6 min 40 sec \n" ); document.write( "

\n" );
