Problem Analysis

We have two people who are packaging buckwheat groats into bags. 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.

Solution

To solve this problem, we need to find the total number of bags required to package 196 kg of buckwheat groats. Since each bag contains 2 kg of groats, we can calculate the number of bags as follows:

Number of bags = Total weight / Weight per bag

Let's calculate the number of bags required:

Number of bags = 196 kg / 2 kg = 98 bags

Now, we can determine how long it will take for the two people to package 98 bags.

The first person can package 4 bags per minute, and the second person can package 3 bags per minute. Together, they can package 4 + 3 = 7 bags per minute.

To find the time required, we can divide the total number of bags by the rate at which they can package bags:

Time required = Number of bags / Bags per minute

Let's calculate the time required:

Time required = 98 bags / 7 bags per minute = 14 minutes

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

Answer

It will take the two people 14 minutes to package 196 kg of buckwheat groats.
