Actual distance between Home and Railway station = 30 Km
Distance between home and railway station in the given map
= 3 + 3 = 6 cm
So, According to scale in the given map
6 cm = 30 Km
We have to find measure of 1 cm
Therefore, dividing both side by 6,
Scale: 6 ÷ 6 cm = 30 ÷ 6 Km
Therefore, Scale is 1 cm = 5 Km.
