For the Queen’s County National Bank problem (problems 22 and 23), Gerald Morris has decided that although he will not revisit any branch, he is willing to drive by a previously visited branch if doing so will decrease his overall driving time.

 a. Find the minimum driving time between each branch pair.

b. Use your result for part a to determine the minimum driving time to visit each branch if Gerald can drive by a previously visited branch.

 c. Assume that Gerald will spend the same amount of time at each branch. Give a minute-by-minute schedule that begins with his leaving the home office at 9:00 A.M. and ends with his return to the home office at 5:00 P.M. Schedule Gerald’s one-hour lunch break to be as close to 12:00 as possible.
