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.

Answer 1

depends on the distance from your toe to your brain.
If it were 1.8 meters
then time = distance / speed = 1.8 /100 = 0. 08 seconds
so about a tenth of a second
