You can put this solution on YOUR website!
9/15 = time = 0.6 hours
\n" ); document.write( "12/x = 0.6 rate in current
\n" ); document.write( "12 = 0.6x
\n" ); document.write( "20 = x
\n" ); document.write( "Rate with Current: 20mph
\n" ); document.write( "Rate without Current: 15mph
\n" ); document.write( "20 - 15 = 5
\n" ); document.write( "Current's Speed: 5mph
\n" ); document.write( "
\n" );
