d = rt is the basic distance equation.
\n" ); document.write( ".
\n" ); document.write( "Boat A travels distance 'd' in time 't' at 30 mph.
\n" ); document.write( "Boat B travels distance 'd' in time 't-2' at 40 mph.
\n" ); document.write( ".
\n" ); document.write( "30t = 40 (t-2)
\n" ); document.write( "30t = 40t - 80
\n" ); document.write( "-10t = -80
\n" ); document.write( "t = 8
\n" ); document.write( "t-2 = 6
\n" ); document.write( ".
\n" ); document.write( "Boat A travels for 8 hrs at 30 mph for a distance of 240 miles.
\n" ); document.write( "Boat B travels for 6 hrs at 40 mph for a distance of 240 miles.
\n" ); document.write( ".
\n" ); document.write( "Since the two boats have traveled the same distance, then Boat B has caught up with Boat A.
\n" ); document.write( ".
\n" ); document.write( "Re-read the question to make sure you answer it.
\n" ); document.write( ".
\n" ); document.write( "What time did Boat B overtake Boat A?
\n" ); document.write( "9 a.m. + 6 hrs = 3 p.m.
\n" ); document.write( ".
\n" ); document.write( "Done. \n" ); document.write( "
