Question

1 работник на 8 станках делает 11 деталей 2 работник на 6 станках делает 15 деталей за какое время они изготовят 1602 детали

Answer 1

11*8=88(дет/час) - делает І рабочий

15*6=90(дет/час) - делает ІІ рабочий

88+90=178(дет/час) - делают І и ІІ рабочий вместе

1602:178=9(часов)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Answer 2

Problem Analysis

We have two workers operating on different numbers of machines and producing different numbers of parts. We need to determine how long it will take for them to produce a total of 1602 parts.

Solution

Let's break down the problem step by step:

1. Calculate the productivity of each worker: - Worker 1 operates on 8 machines and produces 11 parts. - Worker 2 operates on 6 machines and produces 15 parts.

2. Calculate the total productivity of both workers: - Worker 1's productivity: 11 parts/machine * 8 machines = 88 parts - Worker 2's productivity: 15 parts/machine * 6 machines = 90 parts

3. Calculate the total number of parts produced by both workers in one unit of time: - Total productivity: 88 parts + 90 parts = 178 parts

4. Calculate the time required to produce 1602 parts: - Time required: 1602 parts / 178 parts = 9 units of time

Therefore, it will take the two workers 9 units of time to produce 1602 parts.

Answer

The two workers will take 9 units of time to produce 1602 parts.

Explanation

To solve this problem, we first calculated the productivity of each worker by multiplying the number of machines they operate on by the number of parts they produce per machine. Then, we added the individual productivities to find the total productivity of both workers. Finally, we divided the total number of parts required by the total productivity to find the time required to produce 1602 parts.
