Answer:
1 mile
Step-by-step explanation:
We can write a ratio to solve
We know 1 hour is 60 minutes
1/6 mile x miles
------------ = ---------------
10 minutes 60 minutes
Using cross products
1/6 miles * 60 minutes = 10 minutes * x
10 = 10x
Divide by 10
1 = x
1 mile
12/72 is equivalent to 1/6
1/6 of the population are building a nest
1/6 of 10,800 is 10,800/6 which is 1,800
about 1,800 are building a nest
