Plane I x mph
\n" ); document.write( "Plane II x+ 60
\n" ); document.write( "..
\n" ); document.write( "They are moving away from each other
\n" ); document.write( "
\n" ); document.write( "So add up their speed.
\n" ); document.write( "
\n" ); document.write( "combined speed = x+ 1 x + 60
\n" ); document.write( "( 2 x + 60 )
\n" ); document.write( "Time = 5 hours
\n" ); document.write( "Distance = 2800 miles
\n" ); document.write( "Distance = speed * time
\n" ); document.write( "( 2 x 60 )* 5 = 2800
\n" ); document.write( "10 x + 300 = 2800
\n" ); document.write( "10 x = 2800 + -300
\n" ); document.write( "10 x = 2500
\n" ); document.write( "/ 10
\n" ); document.write( "x= 250 mph Plane I
\n" ); document.write( "Plane II 250 + 60 = 310 mph
\n" ); document.write( " \n" ); document.write( "
\n" );
