The speed of a nerve impulse in the human body is about 100 m/s. if you accidentally stub your toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. translation ? lol

Say you were 100 meters tall. In that case, the nerve impulse would reach your brain in about 1 second, since it goes 100 meters per second. You're a little less than 50 times shorter, so the nerve impulse must take a little less than 1/50th of a second. 

In fact, distance traveled = speed of travel * time it takes. Thus, 
time = distance/speed 
==> time = 1.7m/(100m/s) 
==> time ~ 0.017 seconds, or about 17 milliseconds.

I hope my answer has come to your help. Thank you for posting your question here in .
