Question 86180
Your route has traced out two legs of a right triangle. The hypotnuse of the right triangle is the shortest distance from where you are to where you started from and this is given by: c^2=a^2+b^2 which is the Pythagorean Theorem. c is the hypotnuse and a and b are the two legs.

c^2=65^2+75^2

c^2=4225+5625

c^2=9850  take square root of both sides
c=99.247 kilometers
