Default Re: Brain Teasers & Riddles

Upon reflection, I'd like to withdraw this brain teaser. I selected it without really thinking and have since realized that it isn't fair to those who don't live in the United States. I've posted another, less American-centric, and IMO better, puzzle below.


There is a certain hiking trail that runs from Point A to Point B and then on to Point C. Like most trails, this one has signs telling you how far it is to the various points along the way. However, unlike most other trails, these signs are marked in time rather than in distance. These times are based on how long it takes the average hiker to make the trip.

A sign at Point A states that it will take approximately 8 hours to travel all the way to Point C.

There are two such signs at Point B. One states that it will take approximately 5 hours to reach Point C. Curiously enough, the other sign states that it will also take 5 hours to reach Point A.

All the signs are accurate for the average hiker, and the fastest way of getting from Point A to Point C is through Point B. How is this possible?

Point B is in a valley between points A and C that are both higher in elevation relative to point B such that the average hiker is able to get to point B from point A faster because it is downhill. However, the trek to point C from point B takes longer because it is uphill. That right?

You got it. Your turn.

Yep.


The boy is dressed in an American football uniform; the numbers hes reciting have to do with yardage. Yards are counted from endzones toward the middle, so after you cross the 50 yard line they start going down again.

So, for the last two questions:
"45 - 8. The boy said 47". If you're on the opponents 45th yard line and get pushed back 8 yards, you're on your own 47th yard line.

"The next one was 42 + 15. The boy said 43." If you're on your own 42nd yard line and advance 15 yards, then you're on your opponents 43rd yard line.

Unless you play Canadian football. In Canada, where everything is bigger and better than our American counterparts, the football field is 110 yards, thus the 55 yard line is the centre.

... and now for our brainteaser, an easy one.

I have forests but no trees. I have rivers but no water. I have mountains but no rocks. What am I?

I am! That probably gets time for the fastest solution too. Atlas is an alternative answer. You're up!

All right:

A boat catches fire while sailing on the ocean. Everyone, except for the captain, leaves aboard life boats. The captain dives and swims under water for 90 yards. He hears an explosion. When he surfaces, he immediately hears another explosion. The captain is dragged aboard one of the life boats by some sailors. He mentions that he heard two explosions. The sailors state that they only heard one explosion. Both captain and sailors are telling the truth.


How is this possible?
