Question

The scale of a map is given as 1cm: 30 km. Two cities are 4 cm apart on the map. Find the actual distance between these two cities.​

Answer 1

By Proportional Method

Let the actual distance be x

A/Q,

1 : 30 :: 4 : x

→ 1× x = 30 × 4

→ x = 30 × 4 / 1

→ x = 120

Hence, the actual distance = 120 km
