Using proportions, it is found that the ordered pair that represents the location of the layover is (3.75, 1.5).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The flight distance is partitioned in a ratio of 3:1, hence, for both the x and y coordinates, we have that:

L - Nv = 3/4(Ny - Nv)

For the x-coordinate, we have that:

x + 4 = \frac{3}{4}(5 + 4)

x = \frac{27}{4} - \frac{16}{4}

x = \frac{11}{4}

x = 3.75

For the y-coordinate, we have that:

y = \frac{3}{4}(2)

y = \frac{6}{4}

y = 1.5.

The ordered pair that represents the location of the layover is (3.75, 1.5).
