Let rowing speed be S, and current speed, C
\n" );
document.write( "Then rowing with the current gives: 
\n" );
document.write( "Rowing against the current gives: 
\n" );
document.write( "2S = 16 ------ Adding eqs (ii) & (i) 
\n" );
document.write( "S, or rowing-speed = \"highlight_green%28matrix%281%2C4%2C+16%2F2%2C+or%2C+8%2C+mph%29%29\"
\n" );
document.write( "Now, you find the speed of the current! \n" );

\n" );
