\n" );
document.write( "Hi
\n" );
document.write( "Let x and c represent the speed of the boat and current respectively
\n" );
document.write( "Question states***
\n" );
document.write( "  x + c =  48mph  |r = D/t = 48mi/1hr
\n" );
document.write( "  x - c =  32mph  |r = 48mi/1.5hr
\n" );
document.write( "   2x = 80mph
\n" );
document.write( "    x = 40mph, speed of boat.  The current is 8mph (48mph-40mph) \n" );
document.write( "

\n" );
