If the nerve cell connecting the spinal cord to your feet is 1.4 m long, and the nerve impulse speed is 25 m/s, how many seconds does it take for the nerve signal to travel this distance?

Time taken by the nerve signal for travelling this distance seconds

Explanation:

Given,

The length of nerve cell connecting the spinal cord to the feet

Speed of nerve impulse

Time taken for  the nerve signal to travel this distance is equal to the total " length of nerve cell connecting the spinal cord to the feet" divided by "speed of nerve impulse"

Substituting the given values in above equation, we get -

seconds.

Thus , time taken by the nerve signal for travelling this distance seconds
