Answer:
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
