Ответ:

405км

Пошаговое объяснение:

Первый автомобиль ехал 3 часа со скоростью 70 км/ч, следовательно, он проехал 210 км (70км/ч*3ч=210км)

Второй также ехал 3 часа ,но со скоростью 65 км/ч, он проехал 195 км (65км/ч*3ч-195 км)

Складываем и получаем 405 км (210км+195 км)

переведіть на украйінську і зробіть у перекладі правильний порядок слів. :::::: I remember going to the British Museum
one day to read up the treatment for
some slight ailment of which I had a
touch – hay fever, I fancy it was. I got
down the book, and read all I came to
read; and then, in an unthinking
moment, I idly turned the leaves, and
began to indolently study diseases,
generally. I forget which was the first
distemper I plunged into – some fearful,
devastating scourge, I know – and, before
I had glanced half down the list of
“premonitory symptoms,” it was borne in
upon me that I had fairly got it.
I sat for awhile, frozen with horror; and
then, in the listlessness of despair, I again
turned over the pages. I came to typhoid
fever – read the symptoms – discovered
that I had typhoid fever, must have had it
for months without knowing it –
wondered what else I had got; turned up
St. Vitus’s Dance – found, as I expected,
that I had that too, – began to get
interested in my case, and determined to
sift it to the bottom, and so started
alphabetically – read up ague, and learnt
that I was sickening for it, and that the
acute stage would commence in about
another fortnight. Bright’s disease, I was
relieved to find, I had only in a modified
form, and, so far as that was concerned, I
might live for years. Cholera I had, with
severe complications; and diphtheria I
seemed to have been born with. I plodded
conscientiously through the twenty-six
letters, and the only malady I could
conclude I had not got was housemaid’s
knee.
