Answer 2

Calculation of Planting Time for Two Brigades of Workers

To determine how many days it would take for two brigades of workers to plant a certain number of fruit trees, we can use the information provided about the planting capacity of each brigade.

According to the information given, one brigade of workers can plant 600 fruit trees in 10 days, and another brigade can plant the same number of trees in 15 days.

To find out how many days it would take for both brigades to plant the trees together, we can use the concept of work rates. The work rate is the amount of work done per unit of time.

Let's calculate the work rate of each brigade first:

- Brigade 1: 600 trees / 10 days = 60 trees per day - Brigade 2: 600 trees / 15 days = 40 trees per day

Now, let's calculate the combined work rate of both brigades:

- Combined work rate: 60 trees per day + 40 trees per day = 100 trees per day

To find out how many days it would take for both brigades to plant a certain number of trees, we can divide the total number of trees by the combined work rate:

- Total number of trees: 600 trees - Combined work rate: 100 trees per day

Number of days required: 600 trees / 100 trees per day = 6 days

Therefore, it would take both brigades of workers 6 days to plant 600 fruit trees together.
