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 number of pages. Let's calculate the time it takes for both Tanya and Sveta to type one page.

Tanya: 1 page in 15 minutes Sveta: 1 page in 20 minutes

Since Tanya takes less time to type one page compared to Sveta, we can conclude that Tanya works faster.

How many pages will each girl type in 1 hour?

To calculate the number of pages each girl will type in 1 hour, we need to convert the time from minutes to hours.

Tanya: - 1 page in 15 minutes - 60 minutes in 1 hour

To find the number of pages Tanya will type in 1 hour, we can use the following calculation:

Number of pages Tanya will type in 1 hour = (60 minutes) / (15 minutes per page) = 4 pages

Similarly, for Sveta: - 1 page in 20 minutes - 60 minutes in 1 hour

Number of pages Sveta will type in 1 hour = (60 minutes) / (20 minutes per page) = 3 pages

Therefore, Tanya will type 4 pages in 1 hour, while Sveta will type 3 pages in 1 hour.

Please note that these calculations assume that both Tanya and Sveta maintain a consistent typing speed throughout the entire hour.
