Question

Три машинистки напечатали вместе 48 страниц.Одна из них работала 1 час,другая 2 часа, третья 3 часа.Сколько страниц напечатала каждая,если скорость работы у них одинаковая?

Answer 1

1+2+3=6 ч ( все время )
48/6=8 стр/ч ( скорость работы )
8*1=8 стр ( напечатала 1 машинистка )
8*2=16 стр ( напечатала 2 машинистка )
8*3=24 стр ( напечатала 3 машинистка )
Ответ: 8,16,24 СТР

Answer 2

Problem Analysis

We are given that three typists worked together and printed a total of 48 pages. The first typist worked for 1 hour, the second typist worked for 2 hours, and the third typist worked for 3 hours. We need to determine how many pages each typist printed if their work rate is the same.

Solution

Let's assume that the work rate of each typist is x pages per hour. Based on this assumption, we can calculate the number of pages printed by each typist using the formula:

Number of pages printed = Work rate * Time

Using this formula, we can calculate the number of pages printed by each typist as follows:

1. The first typist worked for 1 hour, so the number of pages printed by the first typist is x * 1 = x. 2. The second typist worked for 2 hours, so the number of pages printed by the second typist is x * 2 = 2x. 3. The third typist worked for 3 hours, so the number of pages printed by the third typist is x * 3 = 3x.

Since the total number of pages printed by all three typists is 48, we can write the equation:

x + 2x + 3x = 48

Simplifying the equation, we get:

6x = 48

Dividing both sides of the equation by 6, we find:

x = 8

Therefore, each typist printed the following number of pages:

1. The first typist printed 8 pages. 2. The second typist printed 2 * 8 = 16 pages. 3. The third typist printed 3 * 8 = 24 pages.

Answer

If the work rate of each typist is the same, then the first typist printed 8 pages, the second typist printed 16 pages, and the third typist printed 24 pages.
