If you make a quick diagram, you discover that the distance from your starting point is just the hypotenuse of a right triangle whose legs are 65 and 75 km.
Using the Pythagorean Theorem, we have
c^2 = a^2 + b^2
c^2 = 65^2 + 75^2
c^2 = 4225 + 5625
c^2 = 9850 and
c = square root of 9850 or about 99.25 km
