SAT Question e7133228: Ratios Rates Proportional Relationships And Units answer and explanation with Desmos solution

Choice B is correct. It's given that the speed of a vehicle is increasing at a rate of $7.3$ meters per second squared. It's given to use $1$ mile = $1,609$ meters . There are $60$ seconds in $1$ minute; therefore, $60^2$ or $3,600$ seconds squared is equal to $1$ minute squared. It follows that the rate of $7.3$ meters per second squared is equivalent to $\left(\frac{7.3\text{meters}}{1\text{second squared}}\right)\left(\frac{1\text{mile}}{1,609\text{meters}}\right)\left(\frac{3,600\text{seconds squared}}{1\text{minute squared}}\right)$, or approximately $16.33$ miles per minute squared . The rate, $\text{in miles per minute squared}$, rounded to the nearest tenth is $16.3$.
