Question

a county is in the shape of a rectangle that is 50 miles by 60 miles and has a population of 50,000. what is the average number of people living in each square mile of the county? round your answer to the nearest whole number.

Explanation:

Step1: Calculate county area

The area of a rectangle is $A = l\times w$. Here, $l = 60$ miles and $w = 50$ miles, so $A=60\times50 = 3000$ square - miles.

Step2: Calculate population density

Population density $D=\frac{P}{A}$, where $P = 50000$ (population) and $A = 3000$ (area). So $D=\frac{50000}{3000}=\frac{50}{3}\approx17$.

Answer:
