Sho minamoto: Where's my Garbage?,
Starting here, go 20 m east,
then 9 m north,
then 4 m east.
And Finally, Um I forgot but just go south,
That time your 25 m away from here.
(Why do you need to know where your garbage is anyway)
Objective: " Um I forgot but just go south " how many meters was it. (I Just Want to make Sure)
