                           •  {Step 2):       " 40 km west ["of that point"] " ;        •                                             │<==========================================│  
             
                          •  {Step 3:  [back to airport] = " (40 km − 25 km) " ;

 Note:  To find "total distance traveled:

" 40 km + (40 km) + (40 km − 25 km) " ; 

= " 40 km + (40 km) + (15 km) " ;

= " 40 km + 40 km + (15 km) " ;

= 80 km + 15 km  ;   

=  95 km .
