SAT Question 7d093333: Ratios Rates Proportional Relationships And Units answer and explanation with Desmos solution

Choice A is correct. It's given that $1$ meter = $3.28$ feet . It follows that $1^2\text{square meter}=3.28^2\text{square feet}$, or $1$ square meter = $10.7584$ square feet . Since $1$ hour = $60$ minutes , it follows that $250$ square feet per hour is equivalent to $\left(\frac{250\text{square feet}}{1\text{hour}}\right)\left(\frac{1\text{square meter}}{10.7584\text{square feet}}\right)\left(\frac{1\text{hour}}{60\text{minutes}}\right)$, or $\frac{250\text{square meters}}{645.504\text{minutes}}$, which is approximately $0.3873$ square meters per minute. Of the given choices, $0.39$ is closest to $0.3873$.
