Question

токарь за 1 час обрабатывает 16 заготовок.а его ученик-12.над выполнением задания сначала 3 часа работал токарь,затем токарь и ученик вместе работали в течение 3 часов.сколько всего заготовок они обработали за 6 часов?

Answer 1

токарь  за 1 час-16 з

ученик за 1 час-12 з

токарь 3 ч работал

токарь и ученик вместе -3ч

Сколько они сделали всего-? з

 

1)3х16=48 з

2)(16+12)х3=28х3=84 з

3)48+84=132 з

Ответ: 132 заготовки

Answer 2

1)16*3=48(з)
2)16+12=28(з)
3)28*3=84(з)
4)84+48=132(з)

Answer 3

Calculation of Total Machined Parts

To calculate the total number of machined parts in 6 hours, we need to consider the individual productivity of the lathe operator and their apprentice, as well as the time they spent working separately and together.

Let's break down the given information:

- The lathe operator can process 16 workpieces in 1 hour. - The apprentice can process 12 workpieces in 1 hour. - The lathe operator worked alone for the first 3 hours. - The lathe operator and the apprentice worked together for the next 3 hours.

To calculate the total number of machined parts, we can follow these steps:

1. Calculate the number of parts machined by the lathe operator in the first 3 hours: - The lathe operator can process 16 workpieces in 1 hour. - Therefore, in 3 hours, the lathe operator can process 16 * 3 = 48 workpieces.

2. Calculate the number of parts machined by the lathe operator and the apprentice working together for the next 3 hours: - The lathe operator can process 16 workpieces in 1 hour. - The apprentice can process 12 workpieces in 1 hour. - Together, they can process 16 + 12 = 28 workpieces in 1 hour. - Therefore, in 3 hours, they can process 28 * 3 = 84 workpieces.

3. Calculate the total number of machined parts in 6 hours: - The lathe operator machined 48 workpieces in the first 3 hours. - The lathe operator and the apprentice machined 84 workpieces in the next 3 hours. - Therefore, in total, they machined 48 + 84 = 132 workpieces in 6 hours.

So, the lathe operator and the apprentice together machined a total of 132 workpieces in 6 hours.
