An exponential function has the characteristic that it increases by a constant factor when the independent variable increases by a constant increment. The function you describe is an exponential function.
__
It can be written in the form ...
f(t) = f(0)·2^(t/d) . . . . . where d is the doubling time
given h = 600 - 16t ( add 16t to both sides )
16t + h = 600 ( subtract h from both sides )
16t = 600 - h ( divide both sides by 16 )
t =
when h = 400
t = = = 12.5 seconds
