Question

Первый рабочий за один час делает 32 детали, а второй за 4 часа делает столько деталей, сколько первый за 5 часов. За сколько часов они вместе сделают 216 деталей? краткую запись и решение, пожалуйста! ​

Answer 1

Ответ:

1). выясним сколько деталей первый рабочий изготавливает за 5 часов трудового времени.

32*5=160(д.)

2). теперь выясним сколько деталей за час изготавливает 2 рабочий.

160:4=40(д.)

3). теперь мы выясняем сколько деталей за 1 час делают оба рабочих вместе.

32+40=72(д.)

4). теперь 216 делим на 72 для того чтобы узнать за сколько часов оба рабочих изготавливают за это время

216:72=3(ч)

Ответ: 3 часа понадобится рабочим для того чтобы изготовить 216 деталей.

Answer 2

Problem Analysis

We are given that the first worker can make 32 parts in 1 hour, and the second worker 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 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.

Now, let's find out how many parts the first worker can make in 5 hours:

- The first worker can make 32 parts in 1 hour, so in 5 hours, they can make 32 * 5 = 160 parts.

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

Number of parts made by the first worker + Number of parts made by the second worker = Total number of parts

Let's represent the number of hours it will take for both workers to make a total of 216 parts as 'x'. The equation becomes:

32x + 8x = 216

Simplifying the equation:

40x = 216

Dividing both sides of the equation by 40:

x = 216 / 40

Calculating the value of 'x':

x = 5.4

Since we cannot have a fraction of an hour, we need to round up to the nearest whole number. Therefore, it will take approximately 6 hours for both workers to make a total of 216 parts.

Summary

- The first worker can make 32 parts in 1 hour. - The second worker can make 8 parts in 1 hour. - The first worker can make 160 parts in 5 hours. - It will take approximately 6 hours for both workers to make a total of 216 parts.
