SAT Question d6456c7a: Ratios Rates Proportional Relationships And Units answer and explanation with Desmos solution

Choice B is correct. Since $1$ mile is equal to $1,760$ yards, $1$ square mile is equal to $1,760^2$, or $3,097,600$, square yards. It's given that the park has an area of $11,863,808$ square yards. Therefore, the park has an area of $\left(11,863,808\text{square yards}\right)\left(\frac{1\text{square mile}}{3,097,600\text{square yards}}\right)$, or $\frac{11,863,808}{3,097,600}$ square miles. Thus, the area, in square miles, of the park is $3.83$.
