Question

The scale of a map says that 4cm represents 5m in real life.What is the actual number of kilometers that is represented by 16 centimeters on the map

Answer 1

let's solve using unitary method :

• 4 cm - 5 km

• 1 cm - 5/4 km

• 16 cm - 5/4 × 16 = 20 km

therefore, 16 centimeters on map will represent actual 20 kilometers in real life.
