Problem Analysis

We are given that 5 schoolchildren worked on the garden beds for 2 hours. Each of them was able to weed 3 garden beds in one hour. We need to determine the total number of garden beds weeded by the schoolchildren, as well as the number of garden beds weeded by each schoolchild individually.

Total Number of Garden Beds Weeded

To find the total number of garden beds weeded by the 5 schoolchildren, we can multiply the number of garden beds weeded by each schoolchild in one hour by the number of hours they worked together.

Let's calculate the total number of garden beds weeded by the 5 schoolchildren.

Calculation

Number of garden beds weeded by each schoolchild in one hour: 3 garden beds.

Number of hours worked by the schoolchildren: 2 hours.

Total number of garden beds weeded by the 5 schoolchildren: 5 schoolchildren × 3 garden beds/schoolchild/hour × 2 hours = 30 garden beds.

Therefore, the 5 schoolchildren weeded a total of 30 garden beds.

Number of Garden Beds Weeded by 5 Schoolchildren in One Hour

To find the number of garden beds weeded by the 5 schoolchildren in one hour, we can divide the total number of garden beds weeded by the schoolchildren by the number of hours they worked.

Let's calculate the number of garden beds weeded by the 5 schoolchildren in one hour.

Calculation

Total number of garden beds weeded by the 5 schoolchildren: 30 garden beds.

Number of hours worked by the schoolchildren: 2 hours.

Number of garden beds weeded by the 5 schoolchildren in one hour: 30 garden beds ÷ 2 hours = 15 garden beds.

Therefore, the 5 schoolchildren weeded 15 garden beds in one hour.

Number of Garden Beds Weeded by 5 Schoolchildren in 2 Hours

We have already calculated the total number of garden beds weeded by the 5 schoolchildren, which is 30 garden beds. Therefore, the number of garden beds weeded by the 5 schoolchildren in 2 hours is the same as the total number of garden beds weeded.

The number of garden beds weeded by the 5 schoolchildren in 2 hours is 30 garden beds.

Number of Garden Beds Weeded by 1 Schoolchild

To find the number of garden beds weeded by 1 schoolchild, we can divide the total number of garden beds weeded by the 5 schoolchildren by the number of schoolchildren.

Let's calculate the number of garden beds weeded by 1 schoolchild.

Calculation

Total number of garden beds weeded by the 5 schoolchildren: 30 garden beds.

Number of schoolchildren: 5 schoolchildren.

Number of garden beds weeded by 1 schoolchild: 30 garden beds ÷ 5 schoolchildren = 6 garden beds.

Therefore, each schoolchild weeded 6 garden beds.

Summary

To summarize: - The 5 schoolchildren weeded a total of 30 garden beds in 2 hours. - The 5 schoolchildren weeded 15 garden beds in one hour. - Each schoolchild weeded 6 garden beds.
