4+3=7пакетов в минуту
196:7=28 минут

Answer 2

1) 4+3 = 7 пакетов фасуют два человека за 1 минуту
2) 196 : 7 = 28 минут потребуется чтобы расфасовать всю крупу

Answer 3

Problem Analysis

Two people are packaging buckwheat groats into bags weighing 2 kg each. The first person can package 4 bags per minute, while the second person can package 3 bags per minute. We need to determine how long it will take for them to package 196 kg of buckwheat groats together.

Solution

To solve this problem, we can calculate the total number of bags needed to package 196 kg of buckwheat groats. Then, we can divide this number by the combined packaging rate of the two people to find the total time required.

Calculation

The weight of each bag is 2 kg, so the total number of bags needed can be calculated by dividing the total weight of buckwheat groats (196 kg) by the weight of each bag (2 kg):

Total number of bags = Total weight / Weight per bag = 196 kg / 2 kg = 98 bags

Now, we can calculate the combined packaging rate of the two people by adding their individual rates:

Combined packaging rate = First person's rate + Second person's rate = 4 bags/minute + 3 bags/minute = 7 bags/minute

Finally, we can calculate the total time required by dividing the total number of bags by the combined packaging rate:

Total time required = Total number of bags / Combined packaging rate = 98 bags / 7 bags/minute = 14 minutes

Therefore, it will take the two people 14 minutes to package 196 kg of buckwheat groats together.

Answer

The two people will be able to package 196 kg of buckwheat groats together in 14 minutes.
