Question

С кондитерской фабрики отгрузили мармелад.Всего 20 коробок по 3.1 в коробке и 30 коробок по 1.1кг мармелада.Сколько в среднем весит коробка мармелада?

Answer 1

3100 г х 20 кор. = 62 000 г = 62 кг  весят 20 коробок 

1100 г х 30 кор. = 33 000 г = 32 кг весят 30 коробок

(62 +32) кг : (20 +30) кор. =94кг :50 кор. = 1, 88 кг — в среднем весит одна коробка.

Answer 2

1)1,3*20=26кг
2)1,1*30=33кг
3)26+33=59кг
4)20+30=50коробок
5)59:50=1,18кг

Answer 3

Calculation of the Average Weight of a Box of Marmalade

To calculate the average weight of a box of marmalade, we need to determine the total weight of all the boxes and then divide it by the total number of boxes.

Given the information provided, we have: - 20 boxes of marmalade, each weighing 3.1 kg - 30 boxes of marmalade, each weighing 1.1 kg

To find the total weight of the 20 boxes weighing 3.1 kg each, we multiply the weight per box by the number of boxes: 20 boxes * 3.1 kg/box = 62 kg

To find the total weight of the 30 boxes weighing 1.1 kg each, we multiply the weight per box by the number of boxes: 30 boxes * 1.1 kg/box = 33 kg

Now, we can calculate the total weight of all the boxes by adding the weights of the two groups of boxes: 62 kg + 33 kg = 95 kg

To find the average weight of a box of marmalade, we divide the total weight by the total number of boxes: 95 kg / (20 + 30) boxes = 95 kg / 50 boxes = 1.9 kg per box.

Therefore, the average weight of a box of marmalade is 1.9 kg.
