The sides of the base of a brick are 28 cm and 9 cm, and its height is 6 cm. A snail crawls rectilinearly along the faces of the brick from one vertex of the lower base to the opposite vertex of the upper base. The horizontal and vertical components of its speed $v_{x}$ and $v_{y}$ are related by the equation $v_{x}^{2}+4 v_{y}^{2}=1$ (for example, on the upper face, $v_{y}=0$ cm/min, hence $v_{x}=v=1$ cm/min). What is the minimum time the snail can spend on its journey?
