Question

Ученик изготавливает на 4 детали в час меньше, чем мастер. Ученик работал 3 часа, а мастер 5 часов, и в итоге мастер сделал на 80 деталей больше, чем его ученик. Сколько деталей в час изготавливает мастер?

Answer 1

Ученик изготавливает в час х деталей
Мастер изготавливает в час (х + 4) детале
Ученик за 3 часа изготовил 3х (деталей)
Мастер за 5 часов изготовил 5( х + 4) = (5х + 20) деталей
Уравнение:
5х + 20 - 3х = 80
2х = 80 - 20
2х = 60
х = 30
х + 4 = 34
Ответ: 34 детали изготавливал мастер за 1 час.

Answer 2

Calculation of the Master's Production Rate

To find out how many parts the master produces per hour, we can set up a proportion based on the given information. Let's denote the number of parts the student produces per hour as x.

According to the problem, the student produces 4 parts per hour less than the master. So, the student's production rate can be expressed as (x + 4).

The student worked for 3 hours, so the total number of parts produced by the student is 3 * (x + 4).

On the other hand, the master worked for 5 hours and produced 80 more parts than the student. Therefore, the total number of parts produced by the master is 5 * x + 80.

Since the master produced more parts, we can set up the following equation:

5 * x + 80 = 3 * (x + 4)

Now, let's solve this equation to find the value of x.

5 * x + 80 = 3 * x + 12

5 * x - 3 * x = 12 - 80

2 * x = -68

x = -34

The value of x is -34, which doesn't make sense in the context of the problem. It seems there might be an error or inconsistency in the given information or calculations.
