Answer:
The scale of the map is 1cm : 90km
Step-by-step explanation:
Step-by-step explanation:
the scale is then the ratio
5 cm / 450 km = 1 cm / 90 km
remember, a ratio is a form of fraction, and all the corresponding rules and mathematical calculations apply.
also, we can further caucuses (if necessary). remember
1 km = 1000 m
1 m = 100 cm
so,
1 km = 1000 × 100 = 100,000 cm
therefore,
1 cm / 90 km = 1/9,000,000 cm
