A map is drawn at 1:50,000. What ground distance does 1 cm on the map represent?

  • A.5 km
  • B.5,000 m
  • C.500 m
  • D.50 m

Answer: C

One centimetre on the map stands for 50,000 centimetres on the ground. Dividing by 100 gives 500 metres, so a kilometre of ground occupies two centimetres of paper. Converting the ratio into ground units once, at the start, saves repeating the division for every measurement taken.
