Автор ответа: prettypushkova

Пропорция:

51 км - 3,825 л бензина

168 км - х

Зависимость прямо пропорциональная: во сколько раз больше расстояние, во столько раз больше бензина потребуется.

х = 168 · 3,825 : 51 = 12,6 (л) - расход бензина на 168 км.

Ответ: 12,6 л бензина.

Education in Great Britain Twelve million children attend about 40.000 schools in Britain. There are many children who attend a nursery school from the age of 3, but it is not compulsory. In nursery schools they learn some elementary things such as numbers, colours, and letters. Compulsory education begins at the age of 5 when children go to primary school. It is divided into two periods: infant schools (pupils from 5 to 7 years old) and junior schools (pupils from 7 to 11 years old). In infant schools children don't have real classes. They mostly play and learn through playing. It is the time when children just get some knowledge about the classroom, the blackboard, desks and the teacher. After that, real studying begins. They don't play so much as they did it in infant school. Now they have real classes, when they sit at desks, read, write and answer the teacher's questions. Compuisory secondary education begins when children are 11 or 12 and lasts for 5 years. Secondary school is traditionally divided into 5 forms: a form to each year. Children study English, Mathematics, Science, History, Art, Geography, Music, a Foreign language and have lessons of Physical training. But only three of them all are called "core" subjects (the first ones). At the age of 7, 11 and 14 pupils take examinations in the core subjects. There are 3 types of state secondary schools in Great Britain. They are: 1) comprehensive schools, which take pupils of all abilities without exams. Almost all senior pupils (around 90 per cent) go there; 2) grammar schools, which give secondary education of a very high standard. Entrance is based on the test of ability, usually at 11. Grammar schools are single-sex schools; 3) modern schools, which don't prepare pupils for universities. Education in such schools gives good prospects for practical jobs. After five years of secondary education, pupils take the General Certificate of Secondary Education (GCSE) examination. When they are in the third or in the forth form, they begin to choose their exam subjects and prepare for them. There are also about 500 private schools in Great Britain. Most of these schools are boarding ones, where children live as well as study. Education in such schools is very expensive, that's why only 5 per cent of schoolchildren attend them. Private schools are also called preparatory (for children up to 13 years old) and public schools (for pupils from 13 to 18 years old). Any pupil can enter the best university of the country after leaving this school. The most famous British public schools are Eton, Harrow and Winchester.
