Question

If a crew of 4 workers complete the job in 10 hours, how long will it take 5 workers to complete the same job?

Answer 1

Answer:

It will take 8 hours for the 5 workers to complete the same job.

Step-by-step explanation:

The amount of work done is the same for both crews.

Work = time * workers

Work = 10 * 4      

Work = time * 5

Set the two equal

10 * 4 = time * 5

Divide each side of the equation by 5

10*4/5 = time *5/5

8 = time

Answer 2

Answer:

8

Step-by-step explanation:

It is the same amount of work for the workers.

10 times 4 = 40

Blank times 5 equals 40

8
