Answer:
Answer options
A. Two cities that are 7.5 cm apart on the map are actually 50 km apart.
D. Two cities that are actually 66 km apart are 9.9 cm apart on the map.
Step-by-step explanation:
Step 1
Indicate the scale as shown;
3 cm : 20 km, meaning 3 cm on the map represents 20 km on the ground
A). what does 7.5 cm represent on the ground
Distance on ground=(7.5×20)/3=50 km
B). what does 4 cm represent on the ground
Distance on ground=(4×20)/3=26.67 km
C). what does 45 km on ground represent on the map
Distance on map=(45×3)/20=6.75 cm
D). what does 66 km on ground represent on the map
Distance on the map=(66×3)/20=9.9 cm
Answer:
A Two cities that are 7.5 cm apart on the map are actually 50 km apart.
D Two cities that are actually 66 km apart are 9.9 cm apart on the map.
Step-by-step explanation:
3cm on paper to 20 km on land
Converted to cm.
3cm on paper to 2000000cm on land
If two cities are 3cm apart on paper it's is 20 km apart on land
For A.
So if it's 7.5 cm on paper it is
=( 7.5*20)/3
= 50 km apart on land.
For D.
If it's 66km apart on land
It is (66*3)/20 apart on paper.
= 198/20
= 9.9 cm on paper
It's just a cross multiply problem.
