Advent Reflections: Week 2, Day 5

Week Two Day Five: Priest Above All Problems

“Moses said to his father-in-law, “Because the people come to me to inquire of God. When they have a dispute, it comes to me, and I judge between a man and his neighbor and make known the statutes of God and His laws.” Exodus 18:15-16

If a train leaves New York at 0545 traveling 60mph on the same track to Philadelphia as a train leaving Philadelphia leaves for New York at 0600 headed to New York traveling 45mph leaves on, how much time does the dispatcher have to warn both trains to stop?

Sound like a major issue? Maybe not if you live in Atlanta, but if you are on one of those trains, it is a huge deal. Yet what you see above is a typical story problem from a math book. It is, however, lacking information. For example, how far is it from Philadelphia to New York? How big of a train? After all, it takes longer to stop a 100-car banana train than to stop a 10-car passenger train.

Without that information, can you actually solve the problem? I’m not asking if your math skills are up to the division, multiplication, and addition necessary. You can see, though, that you do not possess all the information to solve the problem at hand.

This is considered a simple problem, one that a fifth grader may find in a math book. What about the problems we face in adulthood? (read more here)
