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?

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)

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
