Problem Statement
Larry can swim from Harvard to MIT (with the current of the Charles River) in minutes, or back (against the current) in minutes. How long does it take him to row from Harvard to MIT, if he rows the return trip in minutes? (Assume that the speed of the current and Larry’s swimming and rowing speeds relative to the current are all constant.) Express your answer in the format mm:ss.
