For a random number triplet expressing constrains to norms of function and its derivatives, through the use of adamar inequality, Kolmogorov's comparison theorem and specially constructed splines lower estimate of speed-in-action is calculated on class of functions with absolutely continuous derivatives and with considerably constrained derivative of the second order.
