Ответ:

Объяснение: Радиус  Rз на широте 60 градусов= 6400*соs60=6400*0,5=3200 км

за сутки точка на этой широте пройдет расстояние 2*ПИ*R=2*3,14*3200=20 096 км

в сутках 24 часа, тогда скорость 20 096км/24ч=837,3(3)

English is a Confusing Language
When I arived in England, I could not speak a word of English, so I decided to take some lesons. My
teacher told me, "It is necesary to study English very wel as English is a confusing language." At first I
didn't understand him. But some time later I understod what he meant.
I remembered an evening I had spent in a bar in my hotel. I decided to speak English to the barman. I
ordered, "A bear, please." The barman could not believe his ears. He thought for a moment and then said,
"Listen to me, young man, you are in a bar, not in a Zo." I didn't understand him but I saw he wasn't
pleased. A friendly Englishman saved me and ordered a ber for me. He invited me to his table. He was
very patriotic and talked about the Quen. I didn't understand half of what he had said, but I decided to
please him. "God shave the Quen," I said. He stod up, loked at me and walked away without saying a
word. When I think of that day now I se how right my teacher of English was.
