Answer:
Given:
1 cm = 1200000 cm
using conversion : 1 km = 100000 cm
[tex]1 cm = 12 \times 100000 cm[/tex]
1 cm = 12 km
or we can write this as:
12 km = 1 cm
306 km = [tex]\frac{1 \times 306}{12} = \frac{306}{12} = 25.5[/tex] cm (by unitary method)
Therefore, the distance between Ny and Boston on map(in cm) is, 25.5 cm
