answer all of my questions... okay, how about this: train leaves chicago at 8am heading west towards Washinton State traveling at 45mph and a train leaves new york towards LA traveling at 55mph, how was this ever relevant in school? first, who still travels by train? (at least in the U.S.) and second, they are on schedules. you would know when they arive by checking the schedule.... okay, i guess i answered my own question... never mind
