Question: If a project requires 120 hours to complete and 4 workers are assigned, how many hours will it take if 6 workers are assigned?

Options:

Correct Answer: 80

Solution:

If 4 workers take 120 hours, the total work is 4 * 120 = 480 worker-hours. With 6 workers, it will take 480 / 6 = 80 hours.

If a project requires 120 hours to complete and 4 workers are assigned, how many hours will it take if 6 workers are assigned?

If a project requires 120 hours to complete and 4 workers are assigned, how many hours will it take if 6 workers are assigned?

Step 1: Calculate the total work in worker-hours. Multiply the number of workers (4) by the number of hours (120). This gives you 4 * 120 = 480 worker-hours.
Step 2: Now, you have the total work needed, which is 480 worker-hours. Next, divide this total work by the new number of workers (6) to find out how many hours it will take. So, calculate 480 / 6.
Step 3: Perform the division. 480 divided by 6 equals 80. Therefore, it will take 80 hours for 6 workers to complete the project.

Work Rate – Understanding how to calculate total work based on the number of workers and time taken.
Proportionality – Applying the concept of proportionality to determine how changes in the number of workers affect the time required to complete a project.
