Page 425 of FE Handbook:

The time to do the repetition N of a task is given by: \[T_N = KN^s\] where,
K = constant
\[s = \dfrac{\ln (\mathrm{learning\ rate,\ as\ a\ decimal})}{\ln 2}\] or, learning rate = \(2^s\)
If N units are to be produced, the average time per unit is given by: \[T_{avg} = \dfrac{K}{N(1+s)}\left[(N + 0.5)^{}(1+s) - 0.5 (1+s) \right]\]
