Answer:

  • A) 1/5 = 4/x

Step-by-step explanation:

The scale is:

  • 1 cm : 5 km

Given:

  • 1 cm ⇒ 5 km
  • 4 cm ⇒ x km

Converted to ratio it is:

  • 1/5 = 4/x

Correct choice is A
  • Let the two cities are x km far apart.
  • 1cm is equal to 5km
  • Distance on map 4cm

Now

[tex]\\ \sf\longmapsto \dfrac{1}{4}=\dfrac{5}{x}[/tex]

  • Cross multiply

[tex]\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{4}{x}[/tex]

Option A is correct
