Answer:
Time taken by the nerve signal for travelling this distance
seconds
Step-by-step 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
