6.05 miles

Step-by-step explanation:

When the question says "the longest distance is between the school and the park", that distance must be the hypotenuse since the hypotenuse is always longer than the legs. Therefore, the legs must be 3.4 and 5. Using the Pythagorean theorem to solve:

a² + b² = c²

(3.4)² + (5)² = c²

11.56 + 25 = c²

36.56 = c²

√36.56 = √c²

6.05 = c

Therefore, the distance from the school to the park is 6.05 miles.
