A particular rat given n trials in a maze can run through the maze in t minutes, where t=6+20/n+2. How many trials are needed so that the rat can runthrough the maze in exactly eight minutes?

Answer 1

ambiguous equation.

Did you mean

t = 6 + 20/(n+2)
or
t = 6 + 20/n + 2 , the way you typed it
or
t = (6+2)/n + 2
or
t = (6+20)/(n+2)

each would give you a different result.

Answer 2

Reiny the problem is t=6+20 over n=+2
