Attention! The cache is not located at the above coordinates. To
find the location of the cache, you need to solve the following
puzzle. The cache is located in the San Rossore Park, which closes
at 7pm. Most of the park is accessible only through guided tours,
but the cache is located in the part that is freely accessibile,
not far from the road that leads to the seaside villa of the
President of Italy.
Attention: If the people at the entrance of the park say that the
park is open only on Saturday and Sunday, you can tell them that
you are going to 'La Sterpaia'. That part of the park you can go to
on any day.
During the 2008 Olympics you are going on a sightseeing trip with
three Chinese friends. You come across a long, old bridge that can
only hold 2 people at the same time. It is dark already and you
only brought one torch. The torch is always needed when walking on
the bridge, so it must be brought back and forth. You and your
friends all walk at different speeds and a pair must walk together
at the rate of the slower man:
Chin takes 1 minute to cross
Ying takes 2 minutes to cross
Ming takes 5 minutes to cross
You take 10 minutes to cross
For example, if you and Ming walk across first, it takes 10 minutes
to cross the bridge. If Ming then returns with the torch, a total
of 15 minutes will have passed. How many minutes will it take at
a minimum before all four of you are on the other side of the
bridge? Answer = 'bc'
