Respuesta :

Answer:

8.25

Explanations:

According to the scale used:

2cm = 3km

Which means that 2cm on the map represents 3km in actuality

The shortest distance from Edgar's house to school according to the map = 5.5 cm

Let the actual distance be represented by x

2cm = 3 km

5.5 cm = x

Do a cross multiplication

2(x) = 3 (5.5)

2x = 16.5

x = 16.5/2

x = 8.25 km

The actual distance = 8.25 km
