Velocity is a vector.
\n" ); document.write( "Let east be positive x, north positive y.
\n" ); document.write( " $\"V%5B2%5D\"$ =( $\"0\"$ , $\"50\"$ )
\n" ); document.write( " $\"V%5B1%5D\"$ =( $\"0\"$ , $\"20\"$ )
\n" ); document.write( " $\"DELTA%2AV=V%5B2%5D-V%5B1%5D\"$
\n" ); document.write( " $\"DELTA%2AV\"$ =( $\"0\"$ , $\"50\"$ )-( $\"0\"$ , $\"20\"$ )
\n" ); document.write( " $\"DELTA%2AV\"$ =( $\"0\"$ , $\"30\"$ ) \n" ); document.write( "

\n" );
