\n" ); document.write( "

Let speed in still water be S, and speed of current, C
\n" );
document.write( "Then upstream equation is: ________S - C = 4 ------ eq (i)
\n" );
document.write( "Also, downstream equation is: _____S + C = 6 ------ eq (ii)
\n" );
document.write( "2S = 10 ------ Adding eqs (i) & (ii)
\n" );
document.write( "S, or speed of canoe, in still water = , or 5 mph\r
\n" );
document.write( "\n" );
document.write( "5 – C = 4 ------- Substituting 5 for S in eq (i) 
\n" );
document.write( "– C = 4 – 5 
\n" );
document.write( "– C = – 1
\n" );
document.write( "C, or speed of current = , or  mph
\n" );
document.write( "You can do the check!!
