Maths Everybody!

I have a tricky question for y'all.. Let's see who'll solve it first!

Imagine you're on a train. This train goes from A to B. It takes 5h to get from A to B. One train goes from B to A every hour.
If you are going to go to B, how many trains will you see on the way?

Show me how you've solved it too..

R) Edited the thing Cyn said..

none. the trains leaving B were never said to be going to A.
if you wanted us to assume that B was going to A...
go F00k yourself.

i'd say ten, but that was just a thought, cuz you'll meet one every hour, and since both trains move they will meet every half an hour. i could be wrong though.. but only if the trains leaving B go to A

I'd say 6. As you are leaving point A, you will see the first one coming in, and when you get to point B, you will see the 6th one leaving.


DID I GET IT, DID IT GET IT!?!?!?!?!?

10

By this logic, I don't think 10 is correct because that is saying that the ratio is 2:1
(train 1 takes 2 hours, while train 2 takes 1 hour)
So train 2 is going 2 times faster

This would be 5:1
(train 1 takes 5 hours, while train 2 takes 1 hour)
Train 2 is going 5 times faster

so it may actually be 25 times.

If you count the trains that is just leaving while you are ariving, that would make it 26

But that can't be right either, because that would be saying that for every 1 hour you would see 5 trains....and that's not right.

[Cyn v4.1]

well, just because a train leaves B every hour does not mean it has to arrive at point A in an hour.

[dwightfry]

I'm sticking with my answer of 6.

For every hour train one goes, 1.2 trains would go into the oppisite direction. so if train 1 goes for 5 hours, that would be 6 full trains.



I got 1.2 because 5 devided by 1 is .2

he edited before you made your second post...

perhaps you now are the fool....

but either way i would say.. 8 because it is a random number that nobody else has chosen so far/...
