Answer:
54.4 kilometers apart
Explanation:
Looking at a compass, it can be found that the direction North and the direction East form a right angle (90 degrees).
This scenario can be depicted as a triangle, where the sisters' travel routes are the legs and their distance apart is the hypotenuse.
The hypotenuse can be found by the Pythagorean Theorem:
![32^2 + 44^2 = c^2](https://img.qammunity.org/2023/formulas/mathematics/college/96g2grl3vyv2emit737l42f0d8wcebbcl3.png)
Solve for c:
![1024 + 1936 = c^2\\2960 = c^2\\\\c = 54.4 km](https://img.qammunity.org/2023/formulas/mathematics/college/9q3thxtt1u0zhk5n9a4i83dmydpfofz5nz.png)
So, the sisters are 54.4 kilometers apart.
