Question

the human nervous system can propagate nerve impulses at about 10 squared metered per second. estimate the time it takes to travel 2 m from your toes to your brain.

Answer 1

Speed of nervous system

$v = 10^2 m/s$

distance from toes to head

$d = 2 m$

now as we know that

$speed = \frac{distance}{time}$

$v = \frac{2}{t}$

given that

$v = 10^2 m/s$

$10^2 = \frac{2}{t}$

on solving the above equation

$t = 0.02 s$

so it will take 0.02 seconds to travel

Answer 2

Use the formular d = v x t
d = 2m
v= 100m/s

t= d / v
 = 2 / 100
 = 0.02sec
