A pilot flew from one office to another. The average speed going is 320mph and returning is 480mph, find the Round Trip distance, if total flying time was 5 hours.
\n" ); document.write( "-----------------
\n" ); document.write( "Avg speed of the round trip is 2*320*480/(320 + 480)
\n" ); document.write( "= 307200/800
\n" ); document.write( "= 384 mi/hr
\n" ); document.write( "---------------
\n" ); document.write( "RT distance = 384 mi/hr * 5 hr = 1920 miles
\n" ); document.write( "
\n" ); document.write( "
\n" );
