вроде бы так, но я не очень уверена)

Приложения:

romaishb: Дано:
S=36 км/ч
t=20 мин
v2=48 км/ч
Найти:
t2-?
Решение:
20 мин - 1/3 ч
1) 36: 1/3=12 (км) - расстояние между населёнными пунктами
2) 12:48=1/4 (ч) - потребуется на обратный путь, т.е. 15 мин
ответ: 15 минут

kykyryska0063: спасибо))

A. Mars, or the 'Red Planet' as it is sometimes known, has a dusty, rocky surface and a thin atmosphere. Its rather calm conditions and short distance to Earth make it the most likely destination for future planet exploration by humans. It has already been visited by a number of Mars robots in successful (and unsuccessful) missions. These highly advanced robots take samples and record important scientific data for scientists back on Earth to study.
B. Venus is similar in size to Earth but a lot hotter! Venus is like an oven thanks to its thick clouds which keep the heat in. Venus is the hottest and the brightest planet with around 500 degrees above zero. Its size is slightly smaller than Earth's. The surface of Venus is often described as a 'stormy desert' full of many craters and very active volcanoes. C. Saturn is a gas giant which is perhaps the most beautiful planet in our solar system (other than Earth of course). It has spectacular ring system. Saturn is the second largest planet in our solar system. The rings are made up of millions of ice crystals, some as big as houses and others as small as water drop. Like Jupiter, Saturn has many moons which surround it.
D. Uranus likes to be a bit different. It is blue-green in colour and rolls like a barrel rather than spinning like Earth and the other planets in our solar system. Uranus turns lying on its side. It was the first planet discovered by telescope. Since Uranus takes 84 Earth years to go around the Sun, this means that each of its poles is in daylight for 42 years and in darkness for the next 42.
