Task Analysis

To solve this problem, we need to determine how many additional workers are required to complete a task in 4 days, given that 8 workers can complete the task in 6 days.

Solution

Let's denote the number of additional workers needed as x.

The formula to calculate the number of workers required to complete a task in a different time is given by: Workers × Time = Constant

Using this formula, we can calculate the number of additional workers needed.

Given: - Workers (W1) = 8 - Time (T1) = 6 days - New Time (T2) = 4 days

We can use the formula to find the number of additional workers needed: W1 × T1 = W2 × T2

Calculation

Substituting the given values: 8 × 6 = (8 + x) × 4

Solving for x: 48 = 32 + 4x 4x = 48 - 32 4x = 16 x = 4

Answer

Therefore, 4 additional workers are needed to complete the task in 4 days.
