Question

Тупой телефон Двое очистили 400 штук картофеля один очистил 3 штуки в минуту другой 2 штуки в минуту 2 работал на 25 минут больше первого Сколько времени работал каждый

Answer 1

Если первый работал х м., то второй работал х+25 м
1) 3* х+ (х+25)*2=400
3 х+2х+50= 400
5 х= 400-50
5 х= 350
х= 70 минут первый работал
2) 70. м+25 м= 95м работал второй
Ответ: 1 ч 10 м работал первый, 1 ч 35 м работал второй.

Answer 2

Calculation of Work Time for Each Person

To calculate the work time for each person, we need to consider the following information:

- The first person can peel 3 potatoes per minute. - The second person can peel 2 potatoes per minute. - The second person worked for 25 minutes longer than the first person.

Let's calculate the work time for each person:

1. Let's assume the first person worked for x minutes. 2. The second person worked for x + 25 minutes.

Now, we can calculate the number of potatoes each person peeled:

- The first person peeled 3x potatoes. - The second person peeled 2(x + 25) potatoes.

Since the total number of potatoes peeled is 400, we can set up the following equation:

3x + 2(x + 25) = 400

Simplifying the equation:

3x + 2x + 50 = 400

5x + 50 = 400

5x = 350

x = 70

Therefore, the first person worked for 70 minutes, and the second person worked for 70 + 25 = 95 minutes.

Answer:

- The first person worked for 70 minutes. - The second person worked for 95 minutes.
