Questions and Answers

What does the scale of a map represent?

  • The actual distance in real life
  • The direction of north on the map
  • A ratio of the distance on the map to the actual distance in real life (correct)
  • A measurement of the size of the map

    • What is the formula to calculate the real distance using a number scale?

  • Real Distance = Measured Distance on Map / Scale Factor
  • Real Distance = Measured Distance on Map × Scale Factor (correct)
  • Real Distance = Scale Factor / Measured Distance on Map
  • Real Distance = Measured Distance on Map - Scale Factor

    • What is the advantage of using a bar scale?

  • It is easier to use than a number scale
  • It adjusts proportionally when resizing maps, maintaining accuracy (correct)
  • It is only used for small maps
  • It is more accurate than a number scale

    • How do you measure the real distance using a bar scale?
