A non-stop flight between two cities averages 460(mph) and takes 2.5 hours.
\n" ); document.write( "The nonstop flight back averages 500 miles per hour because of a tailwind.
\n" ); document.write( " How long does the flight back take, assuming it follows the same flight path?
\n" ); document.write( ":
\n" ); document.write( "find the distance of the flight; dist = speed * time
\n" ); document.write( "460 * 2.5 = 1150 mi
\n" ); document.write( "find the return time when av speed was 500 mph; time = dist/speed
\n" ); document.write( "t = $\"1150%2F500\"$
\n" ); document.write( "t = 2.3 hrs
\n" ); document.write( " \n" ); document.write( "
