And for everyone else, of course, because tourist seems to have gone to bed. No lying guards this time.
1) -3) have been solved
1) Find all times that the hour and minute hand of a clock lie directly on top of each other?
2) With two measuring cups, each holding 4 and 7 units, measure 2 units. Assume that you have an indefinite amount of water.
3) tourist and agardenchair run a 100m dash. tourist wins with an edge of 10 meters. ((Unlikely, you're right.) They repeat the race but this time tourist's starting line is 10m in front of the regular starting line. Assuming their velocities are constant and have not changed, who wins?
Edit: Error in 2) corrected
4) Cross out nine letters to get a single word:
X A S T I D N K G U L N E J W O F R O D
5) A ladder of 10m length is leaning against a wall. It touches a cuboid-shaped crate, sized 1x1x1 m^3, that is standing snugly in front of the wall. At what height does the ladder touch the wall? (There are two possible positions of the ladder, they are symmetrical. Find the greatest height of the two possible.)
6) M. White, W. Black and G. Brown are colleagues and eat at the cafeteria.
"Isn't it remarkable, that we are called 'White', 'Black' and 'Brown' but each also have white, brown or black hair?', says the woman of the three.
"Indeed', answers the person with black hair, 'And did you notice that nobody of us has the hair color that matches his / her name?"
"Gosh, you're right", says M. White.
Suppose the woman's hair is not brown, what color is M. White's hair?

2) I'm not sure I understand the question. Measuring to 2 units with a cup that holds 2 units should be fairly easy?
3) tourist, cause when he finishes 100m you just finished 90m, so you both have 10m left and since he runs faster he will finish earlier.
