A guy sets off to work. The trip is two miles. The traffic is heavy and he only averages 30mph for the first mile. He then hits open road. What speed must he average for the second half of the trip in order to have averaged 60mph for the total journey?
Absolutely correct fellfromtree. Even if he travels the second mile at a billion miles an hour he still cannot average 60mph for the total trip.
Because to average 60mph over two miles you must complete the trip in two minutes. But it took the guy two minutes to do the first mile. So no matter how fast he goes on the second mile the total trip will take longer than two minutes.
Yeah VF done a lot of traveling and figure the times out in my head a lot. GPS spoils people nowdays though.
Oh well noone wants to guess on the riddle⌠Itâs from Alternate Reality, The Dungeon (Atari 8-bit 800xl 130xe). The gargoyle on level 3 asks the question. Answer is Shipwreck!
A woman tries to board a bus carrying a 6ft 2in long curtain pole. The driver wonât let her on because the rules are that nothing can be carried on the bus which is over 6 foot long.
She goes back to the shop buys something extra and then boards the next bus and takes the curtain rod with her without a problem.
3 business men walk into a motel and ask for a room for the night. The front desk asks them if they want separate rooms, or just one large one. All of them men agree to get one room to save money. The price of the room was $30. Each man paid $10 apiece and they went to their room.
Later, the front desk manager realized that there was a special going on which made the room cost only $25 dollars and he had overcharged them by $5. So, the manager took 5 $1 dollar bills and proceeded to the business menâs room. He handed each one of the men a single $1 dollar bill and kept the remainder, the $2 remaining. Therefor, each man had only spent $9 for the room.
$9 x 3= $27
Plus the $2 the manager kept (self tipping)
Equals $29.
Tricky, Yourrid! The $2 should be subtracted from the $27 to make $25. The manager initially receives $30. He then gives $3 back, $1 to each man. He now has $27 because he kept the extra $2 that he should have given them, but didnât because of uneven/awkward distribution.
Correct. You have won one government certified âattaboyâ. You can pick up your certificate at the Ministry of Silly Walks, Attaboy Division. For a slight fee, you can be upgraded to an âattapersonâ, which is the politically correct variant. Just show a copy of this thread at the counter.
Just transpose/simplify. My fatherâs son must be me as I have no brotherâs and sisters. Therefore it becomes this manâs father is me. Therefore the picture must be of his son.
As it turns out I had a dispute about this long ago and phoned MENSA. They got it wrong (Amazing). It was only after I suggested they transpose/simplify that they agreed it has to be his son.
This manâŚ.letâs say this is meâŚhis father (my father) has a son. (Me again) My fatherâs son (Me again)
It cannot be this manâs son, as the man in question (This man in the this manâs father equation) is the son of my father. The brothers and sisters I have none part merely indicates there are no options for other kids being the answer. My father has a son. Me. My fatherâs son is me. period. end of story. And truly, my father has one natural born son. So, who is my fatherâs son? Me.
The question doesnât ask âWho am I?â The identity of the speaker, or riddler if you will, is of no importance. âThe picture must be of his sonâ makes no sense in relation to the question, as there was no âpictureâ in the question.
