Решите : турист 4ч ехал на велосипеде и3часа шел пешком, преодолев60км .найдите скорость туриста, если она втрое меньше его скорости при движении на велосипеде?

4*3,=12; 12+3=15; 60: 15=4; ответ 4 км/ч

ответ:

4 детали в день изготавливал ученик

6 деталей в день изготавливал мастер

пошаговое объяснение:

пусть х деталей в день изготавливал ученик, тогда мастер изготавливал в день (х + 2) деталей.

ученик изготовил за 8 дней 8*х деталей, мастер за 7 дней изготовил   7*(х + 2) деталей.

составим уравнение:

8х + 7 * (х + 2) = 74

8х + 7х + 14 = 74

15х = 74 - 14 = 60

х = 60 : 15

х = 4 (детали) в день изготавливал ученик

4 + 2 = 6 (деталей) в день изготавливал мастер

проверим:

8 * 4 + 7 * 6 = 74

32 + 42 = 74

74 = 74

Hi. Taras,

Well, spring officially starts in March, summer in June, autumn in September and winter in December. But sometimes we have weather from each season all in one day. Because English weather changes so often, there is always something to talk about A remark to a stranger about the weather such as "Not a very nice day, is it?" can often lead to an interesting dialogue

Even poets talk about the weather. For example, the great poet Lord Byron (1788-1824) once said, "I like the weather, when it is not raining. That is, I like two months of every year."
