Answer to the Problem of the Week
for the week of May 2, 2005

Trip Around the U.S.
from Car Talk November 18, 2004

The company that Jack works for just finished a new product. They wanted to promote it across the country. Jack was asked to travel by car to each of the 48 contiguous U.S. states to promote the product. He was told that he could visit each state in whatever order he chose, but the company wanted him to start in Delaware, at their headquarters.

They asked that he visit each state only once. He could not go back into a state he had already visited-this was the "Don't Look Back" product tour. So, Jack sat down at his desk and began to plan his trip.

He realized immediately that it was going to be one long car trip. At that moment, his boss stopped by and said, "Hey, I'm going to join you when you reach your last state. I was born there and I've been looking for a reason to go back and visit. You can leave your rental car there, and I'll fly you back in my private jet."

Since Jack hadn't planned his trip yet, how did his boss know which state was going to be Jack's last state? And, which state would that be?

 


Solution to the Problem:

The boss met Jack in Maine.
Maine is the one state that borders only one other state.
Maine only borders New Hampshire and, of course, Canada.
So, Jack must end his trip in Maine.
