Welcome to a nice walk around the hospital area.
1. Go to position above. Here you will find a pond (with a fountain in the summer). How many bench and baskets are there around the pond?
The number of bench=A
The number of baskets=B
2. N57 43.387 E012 03.186 will take you to a number of wires. How many wires are there from this spot up to the chimney?
The number of wires = C
3. N57 43.241 E012.03.091 will make you end up at a roadsign with a speedlimit on.
The speedlimit = D
4. Walk now to N57 43.205 E012 02.922 and there you will find a bench to sit down at and relax the feet.
Look across the road and you will find a lawn vid fence around. On the lawn is it a triangle with lamps. How many lamps are there at the triangle? And on the fence is yellow signs.
The number of lamps = EF
The numbers on the sign = GH
Now you got all you need to find the cache. Just do some simple math now to find out the coordinates:
(A+D+EF+EF+GH)*B=XXX
(((GH*GH)-A-C)/D)*(A-B))+C+EF)=YYY
Calculate everything above and fill it in here:
N57 43.XXX
E012 02.YYY
The cache is located on a spot where people is walking, so try to be discrete when you take it.
