Answer:

6 days

Step-by-step explanation:

Given:

First condition:

• Worker 1 = 30 construction workers
• Time 1 = 10 days

Second condition:

• Worker 2 = 50 construction workers
• Time 2 = unknown

The problem gives us clue that the workers have thesame rate , thus we can represent each by

Worker 1 × Time 1 = Worker 2 × Time 2

30 × 10 = 50 × T

300 = 50 × T

300 / 50 = T

6 = T

Therefore , it will took 6 days for 50 workers to do the job
