It is determined that the temperature (in degrees Fahrenheit) on a particular summer day between 9:00a.m. and 10:00p.m. is modeled by the function f(t)= -1² +5.5t+81, where t represents hours after noon. How many hours after noon does it reach the hottest temperature? It will be hours after noon. (Round answer to nearest tenth.)
