Step-by-step explanation:

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

We will use the distance formula: “

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

Evaluate:

Evauate:

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.
