Question

Таня печатает одну страницу за 15 мин. а света - за 20 мин. Кто работает быстрее: Таня или света? сколько страниц напечатает каждая девочка за 1 час?

Answer 1

1:15 = 1/15 (стр/мин) - скорость Тани.
1:20 = 1/20 (стр /мин) - скорость Светы.
15<20, 
1/15>1/20,
Таня работает быстрее.
1 ч = 60 мин,
1/15 * 60 = 4 (стр) - напечатает Таня за 1ч.
1/20 * 60 = 3 (стр) - напечатает Света за 1ч.

Answer 2

Таня работает быстрее.
60/15=4(стр)-Таня
60/20=3(стр)-Света

Answer 3

Who works faster: Tanya or Sveta?

Tanya can type one page in 15 minutes, while Sveta can type one page in 20 minutes. To determine who works faster, we need to compare the time it takes for each of them to type the same amount of pages.

Let's assume they both type for 1 hour (60 minutes) and calculate how many pages each of them can type.

Tanya: - Tanya can type one page in 15 minutes. - In 60 minutes, Tanya can type 60 / 15 = 4 pages.

Sveta: - Sveta can type one page in 20 minutes. - In 60 minutes, Sveta can type 60 / 20 = 3 pages.

Therefore, Tanya works faster than Sveta, as she can type 4 pages in 1 hour compared to Sveta's 3 pages.

How many pages can each girl type in 1 hour?

As calculated above, Tanya can type 4 pages in 1 hour, while Sveta can type 3 pages in 1 hour.
