Given:
1 inch : 18 kilometers

Let us use the ratio and proportion method:

a:b = c:d where ad = bc

0.8 inches is 14.4 kilometers

1 : 18 = 0.8 : x
x = 0.8 * 18
x = 14.4 km

1.4 inches is 25.2 kilometers

1: 18 = 1.4 : x
x = 18 * 1.4
x = 25.2 km

2.1 inches is 37.8 kilometers

1 : 18 = 2.1 : x
x = 18 * 2.1
x = 37.8 km
