Answer: 16 cm
============================================================
Step-by-step explanation:
It appears that the map is using centimeters since the village distance is mentioned in kilometers.
The ratio 1:50,000 would then mean 1 cm on paper corresponds to 50,000 cm in real life. Divide by 100,000 to convert from cm to km.
50,000 cm = (50,000)/(100,000) = 0.5 km
This says 1 cm on paper refers to 0.5 km in real life.
Now we have the following steps
1 cm : 0.5 km
16*(1 cm) : 16*(0.5 km)
16 cm : 8 km
Therefore, 16 cm on paper refers to 8 km in real life.
------------------------
A slight alternative
(1 cm on paper)/(0.5 km in real life) = (x cm on paper)/(8 km in real life)
1/0.5 = x/8
1*8 = 0.5*x
0.5x = 8
x = 8/0.5
x = 16 cm on paper corresponds to 8 km in real life.
