At $\"x=0\"$ minutes after takeoff,
\n" ); document.write( "the helicopter is taking off,
\n" ); document.write( "and is at $\"40-2%2A0=40-0=40\"$ miles from its destination.
\n" ); document.write( "So, the distance of the flight is $\"highlight%2840%29\"$ miles.
\n" ); document.write( "When the helicopter reaches its destination it is $\"0\"$ miles from its destination, at it has been flying to its destination for $\"x\"$ minutes,
\n" ); document.write( "with $\"40-2x=0\"$ ---> $\"40=2x\"$ ---> $\"x=40%2F2\"$ ---> $\"x=20\"$ .
\n" ); document.write( "So the flight takes $\"highlight%2820%29\"$ minutes. \n" ); document.write( "

\n" );
