You can think of one boat as standing
\n" ); document.write( "still and the other approaching at the
\n" ); document.write( "sum of their speeds.
\n" ); document.write( "Let $\"+s+\"$ = the speed of the smaller boat
\n" ); document.write( " $\"+s+%2B+4+\"$ = the speed of the larger boat
\n" ); document.write( "-------------
\n" ); document.write( " $\"+9.8+=+%28+s+%2B+s+%2B+4+%29%2A.7+\"$
\n" ); document.write( " $\"+9.8+=+1.4s++%2B+2.8+\"$
\n" ); document.write( " $\"+1.4s+=+7+\"$
\n" ); document.write( " $\"+s+=+5+\"$
\n" ); document.write( " $\"+s+%2B+4+=+9+\"$
\n" ); document.write( "The speed of the smaller boat is 5 mi/hr
\n" ); document.write( "The speed of the larger boat is 9 mi/hr \n" ); document.write( "
