Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.

How to determine the total distance of Mara's run.

In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

  • c is the hypotenuse.
  • a is the adjacent side.
  • b is the opposite side.

Substituting the given parameters into the formula, we have;

c² = 3² + 4²

c² = 9 + 16

c = √25

c = 5 km.

Now, we can determine the total distance of Mara's run:

Total distance = 3 + 4 + 5

Total distance = 12 km.
