Question

If it takes 12 people 3 days to build 72 meters of fence, how many meters of fence can 15 people build in one day?

Answer 1

Answer:

30m

Step-by-step explanation:

First, i would calculate how much can 1 person build in a day:

If it takes 12 people 3 days to build a 72m, it would take (12x3) people to build 72m in 1 day

Or 36 people.

Then 1 person can build 72/36 meters of fence each day

Or 2 meters, so 15 people can build 30m of fence  )15x2)
