Draw linear scales and mark the following distances on them.
(i) 1 cm = 1 km (9 km).
(ii) 1 cm = 100 km (1100 km).
(iii) 1: 500000 (13 km).
(iv) 1: 20000 (250 metres).

Answer
(i) Given, 1 cm = 1 km
Hence, scale is 1 cm to 1 km.
(ii) Given, 1 cm = 100 km
Hence, scale is 1 cm to 100 km.3-
(iii) Given, R.F. = 1: 500000
We know that: 1 km = 1,00,000 cm
1 cm = 5 km
Hence, scale is 1 cm to 5 km.
(iv) Given, R.F. = 1: 20000
We know that: 1 m = 100 cm
1 cm = 200 m
Hence, scale is 1 cm to 200 m.
