A submarine travels an evasive course, trying to outrun a destroyer. It travels 1 km north, then 1 km west, then 1 km north, then 1 km west, and so forth, until it has traveled a total of 41 km. how many kilometers is the sub from the point at which it started?
ps.... this is a very bad evasive course... very predictable
