If 4 workers take 900 hours to finish a project, how long will it take 8 workers to complete the same project?

1 answer:

6 0

Answer: 350

Step-by-step explanation: If you multiply the amount of <em>workers</em> by two, then you divide the amount of <em>time </em>by two, and vice versa. So, in other words, whatever number you multiply the workers by, divide the time by that same number. I hope this helps!
