Question

мастер делает на 10 деталей в час больше чем ученик потому что за 2 часа производит столько же деталей сколько ученик за 4 часа. Сколько деталей мастер в час?​

Answer 1

Ответ:

20 деталей

Объяснение:

Пусть мастер производит х деталей в час, тогда ученик х-10 деталей в час.

по условию задачи

2х=4(х-10)

2х=4х-40

2х=40

х=20

Мастер производит 20 деталей в час.

Answer 2

Calculation of the Master's Production Rate

To determine the number of parts the master produces per hour, we can use the information provided in the question.

According to the question, the master produces 10 more parts than the apprentice in the same amount of time. Specifically, in 2 hours, the master produces the same number of parts as the apprentice does in 4 hours.

Let's denote the number of parts produced by the apprentice in 4 hours as A and the number of parts produced by the master in 2 hours as M.

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

M = A + 10

We also know that A = M/2 since the master produces the same number of parts in half the time.

Substituting this into the equation above, we get:

M = (M/2) + 10

To solve for M, we can multiply the entire equation by 2 to eliminate the fraction:

2M = M + 20

Simplifying further:

M = 20

Therefore, the master produces 20 parts in 2 hours, which means the master's production rate is 10 parts per hour.
