Let's break it up.
\n" ); document.write( "For the first 10 seconds,
\n" ); document.write( " $\"D=v%2At\"$
\n" ); document.write( " $\"D%5B1%5D=20%2810%29=200\"$
\n" ); document.write( "For the next 4 seconds,
\n" ); document.write( " $\"D=v%5Bi%5D%2At%2B%281%2F2%29at%5E2\"$
\n" ); document.write( " $\"D%5B2%5D=20%284%29%2B%281%2F2%29%28-3%29%284%29%5E2\"$
\n" ); document.write( " $\"D%5B2%5D=80-24\"$
\n" ); document.write( " $\"D%5B2%5D=56\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"D=200%2B56\"$
\n" ); document.write( " $\"D=256\"$
\n" ); document.write( "256 meters west of start point
\n" ); document.write( " \n" ); document.write( "

\n" );
