SAT Question 73ddfdac: Ratios Rates Proportional Relationships And Units answer and explanation with Desmos solution

It's given that $1$ furlong = $220$ yards and $1$ yard = $3$ feet . It follows that a distance of $112$ furlongs is equivalent to $\left(112\text{furlongs}\right)\left(\frac{220\text{yards}}{1\text{furlong}}\right)\left(\frac{3\text{feet}}{1\text{yard}}\right)$, or $73,920$ feet.
