Here's a trivial solution in Python

def get_walk(minutes):
    if minutes % 2 != 0:
        # Only even minute times are possible, as you always need to walk the same distance east as west, 
        # andnortha s sound.
        raise ValueError("Only walks with an even number of minutes are possible")

    half = minutes / 2
    return half * ['n'] + half * ['s']

If you add the requirement that you can't walk the same street twice...

def get_walk(minutes):
    if minutes % 2 != 0:
        # Only even minute times are possible, as you always need to walk the same distance east as west, 
        # andnortha s sound.
        raise ValueError("Only walks with an even number of minutes are possible")

    # We'll return a rectangle with width 1, so the two short sides combined take 2 minutes
    # We'll divide the remaining minutes by 2 to know how long the other sides should be.
    length = (minutes - 2) / 2

    return ['n'] + length * ['e'] + ['s'] + length * ['w']
