Question

Первый рабочий за 1 час делает 32 детали а второй за 4 часа делать столько деталей сколько первые за 5 часов за сколько часов они сделают 216 деталей при совместной работе

Answer 1

32*5=160 (дет) изготовит 1 за 5 часов
160:4=40 (дет) изготовит 2 за 1 час
32+40=72 (дет) изготовят два рабочих за 1 час
216:72=3 (ч)
Ответ за 3 часа изготовят два рабочих

Answer 2

1)32/1=32(дет/ч)-скорость 1-ого рабочего
2)32/4=8(дет/ч)-скорость 2-ого рабочего
3)32+8=40(дет/ч)-скорость при совместной работе
4)40*5=200(дет)-сделают совместно за 5 часов
Ответ: 200 деталей

Answer 3

Problem Analysis

We have two workers, the first one can make 32 parts in 1 hour, and the second one can make the same number of parts in 4 hours. We need to find out how many hours it will take for them to make a total of 216 parts when working together.

Solution

Let's calculate the number of parts each worker can make in 1 hour:

- The first worker can make 32 parts in 1 hour. - The second worker can make 32 parts in 4 hours, which means they can make 8 parts in 1 hour.

To find out how many hours it will take for them to make a total of 216 parts, we can set up the following equation:

x/1 + x/4 = 216, where x is the number of hours it will take.

Simplifying the equation, we get:

4x + x = 216

Solving for x, we find:

5x = 216

x = 216/5

x = 43.2

Therefore, it will take approximately 43.2 hours for the two workers to make a total of 216 parts when working together.

Answer

It will take approximately 43.2 hours for the two workers to make a total of 216 parts when working together.
