Question

3 workers can do a job is 28 hours. hpw many mroe workers are needed to do this job is 12 hours

Answer 1

Let's assume that the job requires x workers to complete it in 12 hours.

We can use the following formula:

workers × time = constant

Therefore, for 3 workers to complete the job in 28 hours, we have:

3 × 28 = 84

For x workers to complete the same job in 12 hours, we have:

x × 12 = 84

Solving for x, we get:

x = 7

Therefore, we need 7 workers to complete the job in 12 hours, which is 4 more workers than the initial 3.
