No, it's 100%

Think of it this way. Two different people start walking the exact SAME mountain path at sunrise in opposite directions. One starts at the summit, and the other starts at the base. If both arrive at sunset exactly where the other began at sunrise, what is the probability they passed the same point on the path at exactly the same time?

It's shocking to me that a high majority failed this question

What's the correct answer?

They’d meet at the mid point at the exact same time

Not necessarily at the midpoint, but it is 100% that there will be a spot where she is at the same time each day

I don't care where they meet, nor what time. All I know is that it is guaranteed

Anything that is not mechanical, with repeatable precision

The image that works for me is thinking of two beads on a single string. Place one bead at each end of the string and

It's a semantics disagreement. Some people are reading it as "pick any place

Could be, but that's not what was asked.

Left Shark Coug

That's exactly what was asked.

The question does NOT ask you to pick a point.

once they intersect then they're at the same point and time

Do they intersect at the same point and at the same time on consecutive days?

velocity is a function of the first two variables, and is irrelevant

Sunrise sunset exact times don’t matter

I agree with this.

I get what you're saying, but the question asked for the probability of some

That's obviously not what the question is asking though

2/15/19 2:03pm

How precise are we meant to be with the time?

2/15/19 1:48pm

Oh. Never mind. I was just reading the responses. Now I get it.

It was the “at the same time” that got me

It comes down to how you interpret "same time"

2/15/19 2:03pm

Nope, the first option is still 100%

Yep, it finally clicked.. overthinking strikes again

I'm reading the question as: If there's a rock on the side of the path, what's

For any given rock? Highly unlikely. That there will be 1 rock this holds. 100%

100% certainty is wrong.

What's fascinating is that the example given for the correct answer is

2/15/19 2:24pm

That's because it's an example and not the exact scenario

Jericho

2/15/19 2:38pm

Yep. But still funny that in order to prove the true answer the example has

2/15/19 2:45pm

Doesn't require an impossible scenario. The same example could be used

Yep, we're LDS. We believe in proxies! Someone can be the nun's proxy.
