To find the straight-line distance from Jonathan's house to the park, we can use the Pythagorean theorem. Jonathan walks 4 miles east and 3 miles north, forming a right triangle.

Let \( a = 4 \) miles (east) and \( b = 3 \) miles (north). The distance \( c \) (the hypotenuse) can be calculated as follows:

\[
c = \sqrt{a^2 + b^2}
\]

Substituting the values:

\[
c = \sqrt{4^2 + 3^2} = \sqrt{16 + 9} = \sqrt{25} = 5
\]

Thus, if Jonathan had traveled in a straight line from his home to the park, he would have walked **5 miles**.
