Questions and Answers

What does the scale of a map represent?

  • The size of the map in relation to the real world
  • The measurement of the map's dimensions
  • The distance between two points on the map
  • A ratio of the distance on the map to the actual distance in real life (correct)
  • What is the formula to calculate the real distance using a number scale?

  • Real Distance = Measured Distance on Map / Scale Factor
  • Real Distance = Scale Factor / Measured Distance on Map
  • Real Distance = Measured Distance on Map × Scale Factor (correct)
  • Real Distance = Scale Factor × Measured Distance on Map
  • What is the advantage of using a number scale?

  • It is more complex and requires more calculations
  • It is only used for small distances
  • It is accurate even when the map is resized
  • It is easy to use and requires measuring only one distance (correct)
  • What is the disadvantage of using a number scale?
