You may visit the cities in any order, but you must begin and end in Cairo.
Compare the possible visiting orders, adding the travel cost for each leg and the return to Cairo. The route Cairo → Damanhur → Alexandria → Suez → Cairo costs 153 + 174 + 144 + 133 = EGP 604, which is less than the other possible routes. The most efficient route therefore costs EGP 604.
