Question

Гриша работал за станком 3 часa, а Толя работал 4 часа. Вместе они сделали 44 детали. Сколько деталей сделал Толя, если за 1 час работы они вместе сделали 13 деталей?В ответ запишите только число!

Answer 1

Производительность У  Гришы и Толи одинаковая?
Тогда это пропорция
За 7 часов сделали 44 детали это 6 с небольшим в час
Гриша 19 деталей Толя 25

Answer 2

Problem Analysis

We are given that Grisha worked for 3 hours and Tolya worked for 4 hours. Together, they made 44 pieces. We need to determine how many pieces Tolya made if they made 13 pieces together in one hour.

Solution

Let's assume that Tolya made x pieces in one hour. Since Grisha and Tolya together made 13 pieces in one hour, we can write the following equation:

Grisha's productivity + Tolya's productivity = Total productivity

Grisha's productivity = 13 - Tolya's productivity

Grisha's productivity = (1 hour productivity) * (Grisha's working hours)

Tolya's productivity = (1 hour productivity) * (Tolya's working hours)

Using the given information, we can set up the following equations:

Grisha's productivity = (13 - x) * 3

Tolya's productivity = x * 4

Since together they made 44 pieces, we can write the equation:

Grisha's productivity + Tolya's productivity = 44

Substituting the values, we get:

(13 - x) * 3 + x * 4 = 44

Simplifying the equation:

39 - 3x + 4x = 44

x = 44 - 39

x = 5

Therefore, Tolya made 5 pieces.

Answer

Tolya made 5 pieces.
