We are given that: 3/10 in = 7/8 mi Use cross multiplication to get the scale as follows: 3/10 in = 7/8 mi 3(8) in = 7(10) mi 24 in = 70 mi 24/70 in = 1 mi 1 mi = 0.3429 in
Therefore: unit rate of the map is: 1 mi = 0.3429 in
This means that: each one 1 mile in reality is represented by 0.3429 inches on the map
