the question says same path
And yeah, it's low probability to hit EXACTLY at the waterfall. Same as if I hike up a mountain at the same time you're hiking down. I don't know where will meet, but I know that we will at some point.

POLL: Here's a question from a Critical Thinking class I recently took.

An African or European nun?

I'm just impressed that she can climb and descend at (close to) identical rates.

The goal of the question was to check what assumptions people make and how well they can explain their

Is this a comparison of solar time to the 24-hour clock?

Highly unlikely but not impossible.

There is only one place where she can do this

what am I missing? doesn't it have to be 100%?
The Shazad
2/15/19 11:57am
Same time not same path
USMCdad
2/15/19 11:58am
the question says same path
The Shazad
2/15/19 12:01pm
But she has to hit the same part of the path at the same exact time
USMCdad
2/15/19 12:19pm
Imagine the nun's ghost coming up while she's climbing down. Wherever they
swimbro
2/15/19 12:24pm
True I guess the time of day doesn’t matter
USMCdad
2/15/19 12:30pm
But in that case they are constantly on each other the entire time on the trail
USMCdad
2/15/19 12:31pm
Wouldn't they be going opposite directions?
whirl
2/15/19 2:12pm
It is 100%. Imagine her ghost or a friend or whatever.

This was my thought as well. If they leave at the same time, at some point they
Mikey
2/15/19 12:07pm
I understand it as same time of day, not crossing paths.
crazY
2/15/19 12:29pm
You can't cross paths without being at the same spot at the same time.
Left Shark Coug
2/15/19 12:31pm
That's not true.
crazY
2/15/19 1:15pm
It’s both. Same place at the same time. It has to happen at least once.
Jay Rick
2/15/19 12:37pm
Not without backtracking so technically it would be possible
USMCdad
2/15/19 12:42pm
that's not the question though, it's considering 1 person's movement on the trail on 2 days, not 2 people's on 1 day
byujag
2/15/19 12:38pm
You're way over thinking this. The easiest is to realize that it's the same
Left Shark Coug
2/15/19 12:48pm
I get your argument and agree with it, I just think you're fundamentally changing the original question
byujag
2/15/19 12:51pm
I'm really not. It really is the same question.
Left Shark Coug
2/15/19 12:55pm
You're completely ignoring the "same time" part of it.
Byron McNertney
2/15/19 1:10pm
How could it not be the same time if they are face to face?

Same time *on both days*

Meant for left shark
Dread Pirate Westley
2/15/19 1:26pm
I really can't make this any more painfully obvious than I already have.
Left Shark Coug
2/15/19 1:27pm
Thanks for being condescending, but you clearly have a different interpretation
Dread Pirate Westley
2/15/19 1:38pm
100%, yes. Still the same question.
Left Shark Coug
2/15/19 1:43pm
No, it's not. Your answer works with both a moving point in space and different
Dread Pirate Westley
2/15/19 1:59pm
and there will be one point on the path where they will match
The Shazad
2/15/19 2:03pm
Why are you pre-selecting a point? Just look at the point where they both match.

Dread Pirate Westley
2/15/19 2:08pm
It's crazy that YOU don't get it.

Ok, calm down. If she's face to face with her ghost,
Left Shark Coug
2/15/19 1:58pm
On both days?
Dread Pirate Westley
2/15/19 2:00pm
Is she face to face with her ghost? If she is, the both watches should be

If she and her ghost ascend and descend on consecutive days, do they meet at the

Perhaps if we use an illustration you WILL understand...

Dread Pirate Westley

Yes sir.
crazY
2/15/19 2:00pm
Think of it this way.
Left Shark Coug
2/15/19 1:03pm
That's a clever explanation, but that's not the question
Dread Pirate Westley
2/15/19 1:08pm
I think you have proven yourself a true bsu bronco on this thread.
shimmy
2/15/19 4:15pm
Fair enough.
Dread Pirate Westley
2/15/19 4:19pm
Yep. That’s how I read it.
Jay Rick
2/15/19 12:05pm
the scenario assumes too much to predict that it will happen with any certainty

Dread Pirate Westley
2/15/19 12:34pm
Not exactly. The shift in day length isn’t linear.
Breaded Hamster
2/15/19 12:48pm
The fact that she arrived at her destination *exactly* at sundown on both days
Dread Pirate Westley
2/15/19 12:59pm
pace is irrelevant
The Shazad
2/15/19 1:05pm
But that's not the question. The question is "Estimate the probability the nun
Dread Pirate Westley
2/15/19 1:07pm
then integrate that probability across the full path, and you get 100%
The Shazad
2/15/19 1:11pm
The question isn't whether they'll cross, it's whether they're at the same point
Dread Pirate Westley
2/15/19 1:14pm
if you cross on the same path, then you're at the same point at the same time
The Shazad
2/15/19 1:20pm
Not on both days
Dread Pirate Westley
2/15/19 1:24pm
Haha, no you're not. Timing of breaks, variance in pace throughout the day, etc.
Byron McNertney
2/15/19 1:24pm
see the ghost comparison above - day and pace make no difference
The Shazad
2/15/19 1:28pm
Yes it does. The question is about the time, not the crossing of paths.
Byron McNertney
2/15/19 1:20pm
seriously? am I missing a joke like I did with The Greenrake?
The Shazad
2/15/19 1:23pm
Huh? There's only one nun. She's not going to be face-to-face with herself.
Byron McNertney
2/15/19 1:34pm
it asks if she'd pass the same point on the trail.....
The Shazad
2/15/19 1:42pm
I'm wrong. I was ignoring the parameters of start and stop times. You're right.
Byron McNertney
2/15/19 1:44pm
Yep, she'd have to pass the same tree at exactly 12:03:42 both days. Unlikely.
Byron McNertney
2/15/19 1:18pm
Doubtful.

2/15/19 3:24pm
Swimbro's ghost consideration helps to visualize it happening 100%.
Q-grr
2/15/19 1:15pm
It's 100% that they'll cross paths, but that's not the question. The question
Dread Pirate Westley
2/15/19 1:17pm
You run down as fast as you can, and I will hop, skip walk backwards and change
Q-grr
2/15/19 1:22pm
That's great, but it's not whether or not the paths cross. It's whether or not
Dread Pirate Westley
2/15/19 1:25pm
It isn't Quantum Leap. The travel path will intersect at a single moment in time
Q-grr
2/15/19 1:34pm
I agree, but that's not the question. Does she cross the exact same millimeter
Dread Pirate Westley
2/15/19 1:41pm
Select a person to replicate her exact moves up the day she is decending.
Q-grr
2/15/19 1:55pm
stops for lunch from 12-1 at the shrine midway
calcio
2/15/19 1:09pm
I like it! Except she'd have to stop somewhere between the monastery and shrine
Dread Pirate Westley
2/15/19 1:10pm
Bad choice of words. Maybe a McDonalds, sit in same booth?
calcio
2/15/19 1:56pm
This is my favorite answer, by the way!
Dread Pirate Westley
2/15/19 2:07pm
it appears this is a great question for a critical thinking class
byujag
2/15/19 1:27pm
Haha, yep, the question did it's job.
