Question

Большую корзину Лига может собрать за 40 минут а Рита за 60. Им дали другую корзину и вместе они её собрали за 18 минут. За какое время эту корзину соберёт Лига одна

Answer 1

Ответ:

60мин +40 мин. Ответ:100мин

Пошаговое объяснение:

Правильно 100%

Answer 2

Ответ:

30 минут

Пошаговое объяснение:

1/40 + 1/60 = 1/24 собирают обе девочки за одну минуту

Сосчитаем, за сколько соберут обе девочки первую корзину

1: 1/24 = 24 минуты вся корзина

На сбор второй корзины затрачено обоими девочками 18 минут, значит

18:24 = 3/4 соотношение размеров первой и второй корзины

40 · 3/4 = 30 минут  соберет Лига эту корзину

Answer 3

Problem Analysis

We are given that the League can assemble a large basket in 40 minutes and Rita can assemble the same basket in 60 minutes. They were given a different basket and together they assembled it in 18 minutes. We need to determine how long it would take the League to assemble this basket alone.

Solution

Let's assume that the time it takes for the League to assemble the basket alone is x minutes.

From the given information, we can set up the following equation based on the concept of work:

1/40 (work rate of the League) + 1/60 (work rate of Rita) = 1/18 (work rate when they work together)

To solve for x, we need to find the reciprocal of the sum of the individual work rates and multiply it by the time taken when they work together:

x = 1 / (1/40 + 1/60) * 18

Let's calculate the value of x:

x = 1 / (1/40 + 1/60) * 18 = 1 / (3/120 + 2/120) * 18 = 1 / (5/120) * 18 = 1 / (1/24) * 18 = 24 * 18 = 432

Therefore, it would take the League 432 minutes to assemble this basket alone.

Answer

The League would take 432 minutes to assemble this basket alone.
