Да, я почти самая старшая в классе...

Поможете? А то глюки...

От Заречной до Мухино я шёл 0,8 ч со скоростью 5,5 км/ч, а от Мухино до Каменки ехал на велосипеде 1,4 ч со скоростью 12,5 км/ч. На сколько километров Мухино дальше от Каменки, чем от Заречной?

Я поняла, что надо найти расстояние между Мухино и Каменкой, и из него вычесть расстоние между Заречной и Мухино. Но только как их найти?

Дарлина
S = t х v.
1) 0,8ч х 5,5 км/ч = 4.4 км - От Заречной до Мухино
2) 1,4ч х 12,5 км/ч = 17,5 км - от Мухино до Каменки

3) 17,5км - 4,4 км = 13,1 км

Вроде так))) Если я правельно поняла условие задачи.

Энни
Вы только требуете могли бы и повежливее относиться к форумчанам, то есть ко всем, к тому же как я заметила, в одном посте у вас максимум пять слов.

Dear ...,

We’ve been in Mangalia since 15th of August.
Our hotel is on the seashore. It is The President hotel.
There is also a waterfall near the hotel. I like to swim
in the sea and to swim in the waterfall too.
There are many places to play near the hotel as well. I like my ride to Constanta best. It is a big city and a big
sea port too. I liked to see the sights of the city as well.
At the weekend we went to the park. It was so lovely
there! There were many attractions. I liked to go on
a flight – simulator ride. Yesterday we spent the whole
day in the pool. 
Tomorrow we’re going to go to the cinema.
I would like to see an interesting film.
I’m having a wonderful time here.

See you soon

Love

         Это про телепрограму (кстати про винкс)

My favourite TV series

My favourite TV series is “Winx club”.
It’s a cartoon and it comes from Italy. I watch it every day.
The main characters are six girls (Bloom, Stella, Flora, Musa, Techna and Leila) and they can turn into fairies.
There are more than 100 episodes and one film about “Winx club”. Each episode is about thirty minutes long. I watch it on my computer in English and German. My favourite episodes are the ninth and the eleventh ones.
In the ninth episode Musa saved her friend from fire. In the end of the cartoon she got enchantix and helped her friends.
In the eleventh episode girls went to Flora’s planet. It’s very beautiful. In this episode “Trio Trix” tried to kill Flora’s sister, but she saved her. She got enchantix and helped her friends.
I like these episodes, because Musa and Flora got enchantix.

       Это про то что едим

I’m not usually hungry when I wake up, so I don’t eat much before I go to school. I always eat a boiled egg and a glass of milk for breakfast.
I eat my pocked lunch at school. I usually have ham or cheese sandwiches and some fruit. I sometimes have a chocolate biscuit or a yoghurt.
When I get home from school. I have a biscuit and a glass of water. I sometimes have a bar of chocolate.
I often have meat or pasta in the evening, but on Saturdays we all have bake potatoes. 

Кому надо будет такие с анг. или ним. помогу
