\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let the time taken to return be x hours (LA to Boston)
\n" ); document.write( "The time to go will be x+2/3 hours
\n" ); document.write( "600x = 525(x+2/3)
\n" ); document.write( "600x = 525x + 350
\n" ); document.write( "75x = 350
\n" ); document.write( "x = 350/75 = 4 2/3 hours\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The distance will be   4 2/3 * 600 = 2800 miles.         ANSWER\r
