Answer:

A

Step-by-step explanation:

So, let’s find the distance between the two points.

We will use the distance formula: “

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

We will let (1, 4) be (x₁, y₁) and (4, 7) be (x₂, y₂). Substitute:

d=\sqrt{(4-1)^2+(7-4)^2

Evaluate:

d=\sqrt{(3)^2+(3)^2}

Evauate:

d=\sqrt{18}=\sqrt{9\cdot 2}=3\sqrt2\approx4.2

So, the distance between the two points is 4.2 units.

Since each unit is equivalent to one kilomeer, Alejandro wil need to walk approximately 4.2 kilometers.

So, our answer is A.
