Simple question, answered instantly, 5 km. But then I realized, the hiker could start 4+3/2pi km from the north pole. Then she could turn east, walk a full circle always walking east for 3 km and end up right where she turned east, 4 km from where she started. As far as I know, there is no way on flat ground she could end up any closer than 4 km.<u></u><u></u></p>

If you give up, I found the answer. If I did it right, it isn’t an integer or an integer multiple of pi. Try it first before you ask what I got, good luck.<span class="HOEnZb"><font color="#888888"><u></u><u></u></font></span></p>
