Question

The scale on a map is 1 in: 55 miles. What is the distance on the map between two cities that are 99 miles apart?

Answer 1

Answer:

1.8 inches

Step-by-step explanation:

Create a proportion where x is the distance on the map

$\frac{1}{55}$ = $\frac{x}{99\\}$

Cross multiply and solve for x

55x = 99

x = 1.8

So, the distance on the map is 1.8 inches

Answer 2

Answer:

1.8 inches

Step-by-step explanation:

Scales on a map always represent the direct proportion.

Compare the distances as fractions:

Inches on the map

________________  =  $\frac{1}{55} = \frac{x}{99}$

Miles on the ground

$x = \frac{1x99}{55}$

$x = \frac{99}{55}$

$x = \frac{9}{5} = 1\frac{4}{5}$

x = 1.8 inches
