Answer:
x = 67.5 miles
Step-by-step explanation:
Given:-
- The distance between two cities on map, d = 4.5 cm
- Scale : ( 1 cm -> 15 miles)
Find:-
The actual distance between two cities.
Solution:-
- We can direct proportion ratios to determine the actual distance between the two cities by using the scale of the map.
map actual
Scale : 1 cm -------- > 15 miles
cities: 4.5 cm ----------> x
- The proportional relationship is:
x = (15 miles)*(4.5 cm) / ( 1 cm )
x = ( 67.5 miles )
