Автор ответа: frog981

Ответ:

13+5 = 18 (км/год) швидкість катера за течією

18•2 = 36 (км) за течією катер пройшов

13-5 = 8 (км/год) швидкість катера проти течії

2•4 =8 (км) проти течії катер пройшов

36+8 = 44 км всього катер пройшов шлях

The inuit people
The lives of the Inuit people of North America have changed a lot in 50 years. First, their name: people called them Eskimos, but now they are called Inuits, A____ means “the people”. They lived in igloos in the winter but today many of them live in houses in small towns. They hunted seals — they ate the meat and B____ clothes from the fur. Many of the people still wear seal-skin clothes today because they are very warm. Remember, the weather is extremely cold for many months of the year. 80-year-old Inuit, Mariano Tagalik, C____ us a little about her early life. “Our winter igloos were very warm. We cooked inside so sometimes it got too hot. When I was a child I took D____ most of my clothes when I was in our igloo. In the short summers we lived in seal-skin tents, but I spent as much time as possible playing outside.” To move over the snow, they wore special snowshoes on their feet, but today many Inuits E____ snowmobiles. These machines can travel long distances in a short time. In the past it took them days or weeks to travel the same distance.
