## Abstract

In this paper, we use a perturbation method to obtain an approximation to a saddle-saddle heteroclinic trajectory of an autonomous system of ordinary differential equations (ODEs) arising in the equation in the case of travelling wave solutions (t.w.s.): . We compare the approximate form of the solution profile and speed thus obtained with the actual solution of the full model and the calculated speed, respectively.
