Trains - Back to the Cool Math Games
A passenger train leaves New York for Boston traveling at the speed of 80 km/hr. In half an hour a freight train leaves Boston for New York traveling at the speed of 60 km/hr.
Which train will be further from New York when they meet?

This is not fair... It totally depends on the distance between the two stations. For people not familiar with these cities and the distance between them it may not be that obvious.

Am I the only one who thinks there are missing variables here? or is it my missing knowledge of the geography around NY that is keeping me from solving this problem?

I Love it....

Alrighty,,, I'm going to try to explain this one last time... WHY? I don't know, just for the shear fun of seeing how many of you will STILL NOT GET IT....

THE QUESTION IS A SHAM... IT DOES NOT MATTER THE DISTANCE BETWEEN THE POINTS. LOOK AT IT LIKE THIS. LETS SAY YOU ARE AT ONE END OF YOUR STREET, WE WILL CALL YOUR SIDE "SIDE-A" AND I AM AT THE OTHER "SIDE-B". WE ARE BOTH ON BICYCLES. WE START HEADING TOWARD EACHOTHER. ONE IS TRAVELING FASTER THAN THE OTHER, BUT YOU DO NOT KNOW WHICH ONE. "WHEN WE SMACK INTO EACHOTHER, WHO IS CLOSER TO SIDE "A"??? your focusing on the fact that it is impossible to calculate the distance if you do not have more information, which is obvious. It WOULD be impossible to calculate unless you knew how fast they were going, and the distances between the two, HOWEVER......That's not the case....
THE ANSWER IS """""WE ARE AT THE SAME POINT BECAUSE WE JUST SMACKED INTO EACHOTHER""" NEITHER IS CLOSER, WE ARE AT THE SAME POINT. I MEAN, YOU COULD ARGUE IT SAYING THAT THE BACK OF YOUR HEAD IS CLOSER, BUT COME ON... THE POINT IS THAT THE DISTANCE/TIME RATIO DOES NOT MATTER IF THE 2 TRAINS SMACK INTO EACHOTHER. AT THAT POINT, THEY ARE THE SAME DISTANCE FROM BOTH SIDES....

Get it?

I THINK I explained it well,,,, I dunno
