Question

Токарь должен был обработать 80 деталей к определенному сроку. Он обрабатывал в час на 2 детали больше, чем планировал, и уже за 1 ч до срока обработал на 4 детали больше. Сколько деталей в час обрабатывал токарь?

Answer 1

Х деталей в час обрабатывает
Х-2 - обрабатывает по плану

84 : Х = 80 : (Х-2) - 1

Х`2 + 2{ - 168 =0
X = 12

Answer 2

Calculation of the Number of Parts Processed per Hour

To determine the number of parts processed per hour by the lathe operator, we can use the information provided in the question.

According to the question, the lathe operator processed 2 more parts per hour than planned and finished 4 more parts than required 1 hour before the deadline.

Let's denote the planned number of parts processed per hour as x.

Based on the information given, we can set up the following equation:

x + 2 = x + 4

Simplifying the equation, we find:

2 = 4

However, this equation has no solution. It seems there might be an error or missing information in the question.

Please provide any additional information or clarification so that we can assist you further.
