86 + 77 = 163 км/час - общая скорость1630/163 = 10 час - через 10 часов будет встреча

ПЕРЕВЕДИТЕ ТЕКСТ ЛИТЕРАТУРНО. БЕЗ ПЕРЕВОДЧИКАThere are professions – vocations – and people surrender themselves wholly to these professions. Undoubtedly, the profession of a teacher is one of them.
Even if you want to be a teacher you can’t become a good one. You must be born one. Love for children, an ability to communicate with them, understand and teach them – these are the most important qualities of a genuine teacher. An ability to be a genuine teacher is God’s gift; it’s a talent like the talent of a writer, an artist or a musician. In my point of view it’s even more – it’s fate. I think a teacher is like a sculptor: he moulds a personality out of a child like a sculptor creates a beautiful statue out of clay.
Pedagogy is a very complex and responsible study; probably, no less responsible than medicine. As a patient hands to the doctor the most expensive thing – his life, so parents entrust the teacher with the most valuable creature – their child. And mainly it depends on a teacher what kind of person a child will grow up to be: a genius or a villain. If you have been dreaming of become a teacher since your childhood, it’s not a problem nowadays.
In Russia there are more than 250 teachers training colleges and universities; six of them are in Moscow. Every year thousands of young people graduate from these colleges to come to school on September 1st. According to a survey, more than 70 per cent of students enter these colleges by their own choice, and it is well-known to them what difficult and sometimes ungrateful work is waiting for them after receiving their diplomas. In the process of education when they were asked whether they were sorry about their choice of profession, 60 per cent said that they were not sorry at all. Judging by these facts, I can say that teachers come to school not for money (the salary of a teacher is laughable), but they simply can’t help coming because it’s their vocation to work with children.
The profession of a teacher combines both joy and sorrow.
A person who gets pedagogical training should master a lot of knowledge. But the main thing he should understand is according to what laws and rules the personality of a child develops. The most important of them are love and mercy. Doctors have a rule: “Don’t do harm”. I think teachers must also follow this rule; because there is nothing more valuable than children and it depends on teachers what kind of people the children will become. In my opinion, a teacher is responsible for all his pupils, for, according to Antoine de Saint Exupйry we are answerable for those whom we have tamed.
