\n" ); document.write( "For the same distance, the ratio of times is 1.5:1, or 3:2; that means the ratio of speeds is 2:3.

\n" ); document.write( "If b is the boat's speed and c is the speed of the current, then the upstream speed is b-c and the downstream speed is b+c. So

\n" ); document.write( "\"%28b-c%29%2F%28b%2Bc%29+=+2%2F3\"
\n" ); document.write( "\"3%28b-c%29+=+2%28b%2Bc%29\"
\n" ); document.write( "\"3b-3c+=+2b%2B2c\"
\n" ); document.write( "\"b+=+5c\"
\n" ); document.write( "\"b%2Fc+=+5\"

\n" ); document.write( "The ratio of the boat's speed to the speed of the current is 5:1.
\n" ); document.write( "
