An interesting quiz?

Question

I will post the answer in the additional details after 48 hours, or chose the first correct answer as the best answer

There are 2 Trains , one leaving from Station A to station B and the other from B to A. The first train is travelling at the speed of 40 Km/Hr and the second at 60 Km/Hr. Both the trains will meet exactly after 3 hours.

When train 1 started from station A, a crow took of from the train and flew till he touched the second train, then he took off from the second train and flew till he touched the first train. He kept flying between the trains till both trains met.

Now my question is, what distance did the crow fly?

Answer 1

200 miles. 2(40+60)=200

Answer 2

Same distance that the two trains are traveling:

3(40 +60) =300 km

Answer 3

was he near the front or the back? how long were the trains

Answer 4

VARIABLE ANSWER.

The speed of the crow is not given in the problem, so any given speed would do..  say 10 kph, 15 kph, etc..

then you just have to multiply the crow's speed to the exact time when both trains met and you'll find the answer! That will do the trick.

Answer 5

this ones sounds just too wicked to even try

Answer 6

Not enough variables to form a solution to your problem.

Answer 7

He didn't go any distance at all ?

Answer 8

zero...

Answer 9

3 hours.

Answer 10

It was interesting until you spelled "OFF" wrong.

"a crow took off from............"

Nothing ruins a riddle more than bad spelling.

Answer 11

the interesting thing is that we dont know the crow's speed- can you tell us that? How else would the answer be determined because obviously the crow cant fly as fast as the trains are traveling....which means there is no way to know how much closer the trains get while the crow is flying between them.

UNLESS you count the entire distance the crow would fly- which is 300 km. But wouldnt it be more if he was flying back in forth untill the trains met? I would still need to know the crow's speed.

Answer 12

my answer is who cares?

Answer 13

you would need to know how fast the crow was flying and if the train tracks were in a straight line  . .otherwise I'm pretty sure it's impossible

Answer 14

120 km, as the crow flies.

No variable for the crows speed, so must be a "trick" question. Trains meet 120 km away from Station A (3 hours at 40 km/h) so ...120 km

UPDATE AT 24/4/08.

C'mon everyone.

You've got four possibilities given that the crow's speed is unknown.

1) The crow flies slower than Train 1 - in that case he never gets to fly between the trains. Unsolvable (ever).

2) The crow flies at the same speed as Train 1. He flies with the train until they meet. (Solvable)

3) The crow flies faster than Train 1 but slower than Train 2. He never gets to the meeting point. (Unsolvable)

4) The crow flies faster than both trains, He flies between them until they meet. (Solvable, if crow's speed is known).

Question as phrased must therefore be a trick.

Hence "as the crow flies, 120 km".

Otherwise, why not " a bird took off from the train"
