On the horns of a dilemma:

As some already know Mrs. Graybeard and I live in central Illinois. I am an old retired guy but she still works. Her job requires her to be in far off and exotic places from time to time and for the few weeks preceding the cruise she will be in the exotic city of Oklahoma City, Oklahoma.

On the morning of May 10th. she will leave that fair city at 7:00AM. with the destination of St. Louis, Missouri being her immediate goal, a distance of 500 miles, she will be traveling at 70 miles per hour.

I will be traveling toward St. Louis on that same day, a distance of 172 miles at 70 miles per hour with the goal being to meet her there. Then we will travel together southward towards Ft.Lauderdale, Florida.

I need to know what time I should leave here to meet her in St. Louis as she arrives there.

I've been mulling this over for several days and cursing the inadequate public education I received but with the knowledge that when I learned about similar problems when I was in the 6th grade it was in another century and the problems given us always involved trains converging, not cars. If my wife and I were traveling on trains, I reckon I could do this as easy as pie.

We had cars in those days too, though I think they were called horse-less carriages but could they ever use cars as examples? Noooo. It had to be trains.

So if anybody reading this has a modern day 6th. grader handy, please present him/her with my problem but don't tell them about my abysmal education. Tell them instead that old Graybeard would solve it himself but he fell down yesterday and hurt his leg.
