my favorite was what I did in high school...... we had that question:
"Train A leaves charlotte heading east at 110mph, train B leaves Raleigh at 140mph 20 minutes later.... at what time will they pass".
My answer (I was working for the RR at the time):
Never..... there's no locomotive capable of those speeds in operation here, and the speedlimit is 15mph around the curve leaving Raleigh..... it would wreck. Also.... When you pass the scanner around the 161 milepost (same stuff you track the camaro's with)..... it records your speed, do 140mph in a 49mph zone..... it will immediately contact the "higher ups".......
and the teacher had the nerve to say I was wrong???
