The speed of propagation of the action potential $($an electrical signal$)$ in a nerve cell depends $($Inversely$)$ on the diameter of the axon $($nerve fiber$).$ If the nerve cell connecting the spinal cord to your feet is $0\mathrm{.}7m$ long, and the nerve impulse speed is $19\frac{m}{s},$ how long $($in s$)$ does it take for the nerve signal to travel this distance?
