Let the number of hours be x.
\n" ); document.write( "Distance traveled by the first boat=8x
\n" ); document.write( "Distance traveled by the second boat=5x
\n" ); document.write( "Total distance=8x+5x=13x
\n" ); document.write( "Total distance=39 miles
\n" ); document.write( "13x=39
\n" ); document.write( "x=3 hours
\n" ); document.write( "In 3 hours they will be 39 miles apart.
\n" ); document.write( "
