To Study the Rate at Which Animals Learn, a Psychology $n ^ { t h }$

Short Answer

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 $n ^ { t h }$ trial was approximately $T ( n ) = 8 + \frac { 4 } { n } - \frac { 8 } { n ^ { 2 } }$ minutes. How long does it take the rat to traverse the maze in the second trial?
