The Maths Prof: Using Map Scales

In this lesson I show you how to use map scales in ratio form 1 : n. The questions involve length, area and volume. In case you would like to skip to a specific question, here's the breakdown 👇
Question 1 On a map of scale 1 : 100000, the distance between two towns is 6.3 cm. What is the actual distance in km?
Question 2 On a map of scale 1 : 50000, the distance between two towns is 8 cm. What is the actual distance in km? 02:40
Question 3 The distance between 2 towns is 32 km. How far apart will they be on a map of scale 1 : 50000? 04:06
Question 4 On a map, a lake has an area of 32 cm². The scale of the map is 1 : 24000. Calculate the actual area of the lake. Give your answer in km². 06:33 ('Extended' IGCSE exam question paper 2 Cambridge 0580)
Question 5 A map is drawn to a scale of 1 : 100000. Find the area in km² of a village which is represented on the map by an area of 600 cm². 08:41
Question 6 A map is drawn to a scale of 1: 100000. The area of a village is 750 km². Find the area of the village on the map in cm². 10:30
Question 7 A model of a car has a scale of 1 : 20. The volume of the actual car is 12 m³. Find the volume of the model. Give you answer in cubic centimetres. 12:25 ('Extended' IGCSE exam question paper 2 Cambridge 0580)
