If the scale of a map is 2cm to 1km, what is the ground distance if the distance between two towns on the map is 20cm
5km
2.5km
10km
20km
Explicació
map distance = 20cm, ground distance = Y
map scale = 2cm to 1km
since 2cm ≡ 1km
20cm ≡ Y
2Y = 20km
Y = 20km/2=10km
The ground distance between the two towns is 10km
map scale = 2cm to 1km
since 2cm ≡ 1km
20cm ≡ Y
2Y = 20km
Y = 20km/2=10km
The ground distance between the two towns is 10km
