Answer 1

To find the distance between points A(0, 0) and B(6, 3), we can use the distance formula:

\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

Here:
- \( (x_1, y_1) = (0, 0) \)
- \( (x_2, y_2) = (6, 3) \)

Plugging the coordinates into the formula:

\[
d = \sqrt{(6 - 0)^2 + (3 - 0)^2} \\
d = \sqrt{(6)^2 + (3)^2} \\
d = \sqrt{36 + 9} \\
d = \sqrt{45}
\]

Now, simplifying \(\sqrt{45}\):

\[
\sqrt{45} = \sqrt{9 \cdot 5} = 3\sqrt{5}
\]

Using a calculator to approximate \(\sqrt{5}\) (which is about 2.236):

\[
3\sqrt{5} \approx 3 \cdot 2.236 \approx 6.708
\]

Rounding to the nearest tenth gives us:

\[
\text{Distance} \approx 6.7
\]

So the distance between cities A and B is approximately **6.7**.
