distance = 2700
\n" ); document.write( "speed of one plane = 200 mph
\n" ); document.write( "speed of other =250 mph\r
\n" ); document.write( "\n" ); document.write( "they are moving towards each other
\n" ); document.write( "so add up speeds
\n" ); document.write( "250+200 = 450 mph\r
\n" ); document.write( "\n" ); document.write( "distance = 2700\r
\n" ); document.write( "\n" ); document.write( "time = d/r
\n" ); document.write( "2700/450
\n" ); document.write( "=6 hours
\n" ); document.write( "
\n" );
