HINT

  • The sum of the flight times in the route A →→ B →→ C: 1+3=4 hours
  • The sum of the flight times in the route A →→ C →→ C: 4+3=7 hours
  • The sum of the flight times in the route B →→ A →→ C: 1+4=5 hours
  • The sum of the flight times in the route B →→ C →→ A: 3+4=7 hours
  • The sum of the flight times in the route C →→ A →→ B: 4+1=5 hours
  • The sum of the flight times in the route C →→ B →→ A: 3+1=4 hours

The minimum of these is 4 hours.
