Answer 1

The question you asked is in Ukrainian, and it is a math problem. Here is the translation of the question from Ukrainian to English, using one of the web search results:

Answer in detail. A lathe apprentice processes 8 parts in 1 hour. In 5 hours, he processes as many parts as the master in 2 hours. How many parts does the master process in 1 hour?

To solve this problem, we can use the work-rate equation, which is explained in another web search result. The work-rate equation is:

1/A + 1/B = 1/T

where A is the time for the apprentice to do the job alone, B is the time for the master to do the job alone, and T is the time for them to do the job together.

We are given that the apprentice processes 8 parts in 1 hour, so A = 1/8. We are also given that in 5 hours, the apprentice and the master process the same number of parts as the master alone in 2 hours. This means that T = 5 and B = 2. Substituting these values into the work-rate equation, we get:

1/(1/8) + 1/2 = 1/5

Simplifying and solving for B, we get:

B = 40/9

This means that the master can process 40/9 parts in 1 hour.
