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
