Answer 2

To solve this problem, let's break it down step by step.

Given information:

- Malvina, Buratino, Piero, and Arlekin decided to water a flower bed with daisies. - In the morning, they watered a part of the flower bed and got very tired. - After lunch, only Malvina and Piero watered the flowers and finished the job by the end of the day. - They watered the flowers at the same speed for 3 hours in the morning and 3 hours after lunch. - The flower bed had a total of 512 daisies.

Solution:

Let's assume that the part of the flower bed they watered in the morning is represented by the variable x (in daisies). Therefore, the part of the flower bed they watered after lunch is represented by 512 - x (in daisies).

Since they watered the flowers at the same speed for 3 hours in the morning and 3 hours after lunch, we can set up the following equation:

3x = 3(512 - x)

Simplifying the equation:

3x = 1536 - 3x

Adding 3x to both sides:

6x = 1536

Dividing both sides by 6:

x = 256

Therefore, they watered 256 daisies in the morning and 512 - 256 = 256 daisies after lunch.

To summarize: - The friends completed half of the work in the morning and the other half after lunch. - They watered 256 daisies in the morning and 256 daisies after lunch.

I hope this helps! Let me know if you have any further questions.
