Answer: 17 miles
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
A county has a population density of 257 people per square mile.
The proportion is : 257 people / 1 square mile
For 4288 people: 4288 people / x miles
So:
257 people / 1 square mile = 4288 people / x miles
257/1 = 4288 /x
Solving for x
x = 4288/ (257/1)
x = 16.68 = 17 miles (rounded)
