РЕШЕНИЕ
1) 4 +2 = 6 мин - летел горобец
2) 6000 м :6 мин = 1000 м/мин - скорость горобца (кто такой - пусть летит)
3) 9 км : 6 мин = 1,5 км/мин = 1500 м/мин - скорость ласточки
4) 1500 - 1000 = 500 м/мин - разность скоростей
ОТВЕТ: Скорость ласточки больше на 500 м/мин

New Zealand is a member of the Commonwealth of Nations. Though New Zealand is an independent state the British Queen is the head of state there, so, the country is a constitutional monarchy and a parliamentary democracy. Its form of government reflects its historical link with Great Britain. The Queen is represented by the governor-general. Like in Great Britain, the Parliament represents the legislative branch though the Parliament in New Zealand has only one chamber, the House of Representatives. There are 120 members and they are elected by the people.

The main political parties are the National Party and the Labour Party. The leader of the party that has the majority of seats in the House becomes prime minister. He appoints ministers, heads of the formal Executive Council and the informal but influential Cabinet.

The British monarch appoints the governor-general who is part of the Executive Council. New Zealand has no written single constitutional document. The Constitution Act of 1986 determines the distribution of powers: legislative, executive and judicial.
