Reasoning and answer: If the duck takes 40 days to fly to the south during winter and twice as much time to fly to the north during summer, it takes 40 * 2 = 80 days to travel to the north. The total time it takes to travel to the south and the north during both seasons is 80 + 40 = 120 days. The duck also takes 60 days to travel to the East during spring, making the total time it travels during all the seasons to be 120 + 60 = 180.
The answer: 180
