Question

Look at the question below

Answer 1

D = 18 miles

Explanation:

The coordinate of a library = (4,3)

The coordinate of the school = (-5,3)

We need to find the distance between the library and the school. We can use the distance formula i.e.

`D=√((x_2-x_1)^2+(y_2-y_1)^2)\\\\=√((-5-4)^2+(3-3)^2)\\\\=√(81)\\\\=9\ miles`

As the distance between each unit represents 2 miles. It means the distance is 2(9) = 18 miles

So, the correct option is (c).
