Answer:1.5 km
Step-by-step explanation:
Given
Each unit on the grid measures [tex]0.5 km[/tex]
If the coordinates of the point are [tex](2,-9)[/tex] and [tex](5,-9)[/tex]
then distance between them is given by
[tex]d=\sqrt{(5-2)^2+(-9-(-9)^2)}[/tex]
[tex]d=\sqrt{3^2+0^2}[/tex]
[tex]d=3\units [/tex]
and each unit is [tex]0.5 km[/tex]
therefore distance [tex]=0.5\times 3=1.5\ km[/tex]
The distance between the two monuments 1.5 km.
Important information:
- Arc de Triomphe is located at (2,−9).
- Les Invalides is located at (5,−9).
- Each unit on the grid represents 0.5 kilometers.
We need to find the distance between the two monuments in kilometers.
Distance between two point:
The distance between (2,−9) and (5,−9) is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]d=\sqrt{(5-2)^2+(-9-(-9))^2}[/tex]
[tex]d=\sqrt{(3)^2+(0)^2}[/tex]
[tex]d=3[/tex]
Each unit on the grid represents 0.5 kilometers. So, the actual distance is:
[tex]3\times 0.5=1.5[/tex]
Therefore, the distance between the two monuments 1.5 km.
