Question

On a particular map, $3$ inches on the map equates to $10$ miles in real life. If you know that the real life distance between two buildings on the map is $53.25$ miles, what would the distance between the buildings be (in inches) on the map, expressed as a fraction?

Answer 1

Answer: 15 39/40

Step-by-step explanation:

If we let the distance between the buildings on the map be $d$, then $\frac{d}{53.25} = \frac{3}{10}$. Cross-multiplying and solving for $d$, we obtain $10d = 159.75 \Rightarrow d=15.975$ inches. Expressed as a fraction, $d = 15\frac{975}{1000} = \boxed{15\frac{39}{40}},$ or $\boxed{\frac{639}{40}}$ inches.
