Ответ:

240 км

Пошаговое объяснение:

Первый путь за 4.8 ч при скорости V км/ч и расстояние X км. Второй пусть за 5 ч при скорости (V+10) км/ч, расстояние X+60 км. Решим систему уравнений.

4.8 \times v = x \\ 5 \times (v + 10) = x + 60 \\ 5v + 50 = 4.8v + 60 \\ 0.2v = 10 \\ v = 50

Скорость 50 км/ч

4.8 \times 50 = 240

Расстояние от Минска до Орши 240км

КАК МОЖНО СКОРЕЕ!!! ПОЖАЛУЙСТА!!!! МОЛЮ!!!
My friend is a very nice girl with a charming smile.
I think that every person must have a close friend, a true friend, with whom he can share his ideas, problems, and he or she is always ready to listen to you and help you. As for Julia, I can always rely on her, she is a very reliable person and I am pretty sure she will never let me down. She has a good ear for music and we go to a musical school together. She wants to become a musi-cian, and I am sure she will be able to manage it, as she is a very purposeful girl.
Talking about hobbies, I would say that I am fond of reading. I can say I adore reading. My favourite writer is Remark, and my favourite book is "Three Friends" by Remark. I appreciate the friendship of these "three friends", their relationship, and how they care about each other and help each other out of the difficult situations. I think a good example of friendship is shown in this book. I also like dancing, and I dance much. I regard it as an essential part of myself, and I think it can be called a sort of a sport activity, as it helps me keep fit.
I also adore travelling. I think that it is a hobby of my dream. There are so many countries that I am eager to visit. I like nature and during my summer holidays I don't miss any chance to go to the country. And in the country I look forward to my coming back to the big city and going on my routine every day activities.
And talking about my daily routine I want to confess that it is not quite organized. And every Monday when I am awake I think I should start a new life. I honestly think that I must become well-organized and correct my daily routine. I make plans to go to keep fit classes, to do the cleaning and do hundred other good things. But then I remember that I have to call on my friend in the evening, and I put off my plans till next Monday. It is always better to start a new life in a week.
