As a world-class fan of major league baseball, you have always wanted to watch a game in person at each of the ballparks across the country. Now that you are about to graduate, you have decided it is time to achieve this goal. To do so, you must first know the location of each ballpark, when ball games are scheduled, and the driving distance between parks. The Internet can give you all this information.

Decide on a priority rule for building your schedule. You will drive between ballparks, so be sure to leave enough time to reach the next ballpark. You can average 60 miles per hour when traveling on the open road and cover up to 600 miles each day. You must visit each of the major league ballparks during the course of one season. Since you do not graduate until the end of May, you cannot start your adventure until June 1. Your objective is to minimize the total amount of time it takes to visit each ballpark and to minimize the number of miles you drive. You must include any time it takes to return home. You are constrained to driving no more than 10 hours or 600 miles per day. Use the Internet to find the locations of each ballpark, the scheduled baseball games, and the mileage between cities.
