Central Park in New York City is rectangular with a length of 2.5 miles and a width of 0.5 during an afternoon it's population density is about 15 acre find the number of people in the park that afternoon one square mile is equal to 640 acres

12,000 people were present

Step-by-step explanation:

In this question, we are asked to calculate the number of people in a park on an afternoon given the measurements of the park and its population density.

Firstly, we calculate the area of the park.

Mathematically the area is the product of the length and width = 0.5 * 2.5 = 1.25 square miles

Let's convert this to acres. From the question, we know that one square mile is 640 acres, this mean that 1.25 square mile would be 1.25 * 640 = 800 acres

Now let's consider the population density of 15 people per acre, the number of people present is thus 800 * 15 = 12,000 people
