I agree. The other person's setup is PURE RUBBISH!!
\n" );
document.write( "Let the speeds of the boat in calm water, and current, be S and C, respectively
\n" );
document.write( "Then we get the following AVERAGE-SPEED equations:
\n" );
document.write( "2S = 120 ------ Adding eqs (i) and (ii)
\n" );
document.write( "Speed of  boat, in still water, or 
\n" );
document.write( "Now, substitute 60 for S in eq (i) and solve for C to get speed of the current. \n" );
document.write( "

\n" );
