To study the rate at which animals learn, a psychology student performed an experiment in which a rat was sent repeatedly through a laboratory maze. Suppose the time required for the rat to traverse the maze on the nth trial was approximately $T ( n ) = 5 + \frac { 2 } { n } - \frac { 4 } { n ^ { 2 } }$ minutes. How many minutes does it take the rat to traverse the maze on the 2nd trial?

The Answer of To study the rate at which animals learn, a psychology student performed an experiment in which a rat was sent repeatedly through a laboratory maze. Suppose the time required for the rat to traverse the maze on the nth trial was approximately $T ( n ) = 5 + \frac { 2 } { n } - \frac { 4 } { n ^ { 2 } }$ minutes. How many minutes does it take the rat to traverse the maze on the 2nd trial?
