Question

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

We can estimate it like this: In the case of the nerve impulse, this one would reach your brain in about 1 second Because since it goes 100 meters per second then it will take only thar time. If You were a little less than 50 times shorter, so the nerve impulse must take a little less than 1/50th of a second. If you need to do this calculation again you can use the following formula: distance traveled = speed of travel * time it takes. If this is true so
time = distance/speed. I hope this can help you
