    The answer is 2.5 miles.

    To answer this question, you need to use the Pythagoras theorem, which is: a square + b square = c square.

    A is 2.1 miles. 2.1 squared is 4.41.

    B is 1.3 miles. 1.3 squared is 1.69.

    If you add those two, it becomes 6.1.

    The square root of that (you'll need a calculator) is 2.4698 ..., which, rounded to the nearest tenth of a mile is 2.5
