Question

A linen service is delivering clean tablecloths to restaurants on its list of clients. A delivery is made to a restaurant in Oak Grove and then another in Newberry. On a map, these two are 9 inches apart; in real life, the distance is 3 miles. What is the map's scale?Use integer numbers.

Answer 1

To find the map's scale, use the formula below:

$\text{map scale = }\frac{\text{ map distance}}{\text{ distance on the ground}}$

In this exercise,

map distane = 9 inches

distance on the ground = 3 miles.

So, the map scale is:

$\begin{gathered} \text{map scale = }\frac{\text{9 inches}}{\text{ 3 miles}} \\ \end{gathered}$

Dividing both numerator and denominator by 3:

$\begin{gathered} \text{map scale = }\frac{\text{9/3 inches}}{\text{ 3/3 miles}} \\ \text{map scale = }\frac{3\text{ inches}}{\text{ 1 miles}} \end{gathered}$

The map scale is: 3 inches : 1 mile.
