Question

The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 2.00 m tall and that the nerve impulse travels at uniform speed.)

Answer 1

0.02 s takes the nerve impulse to travel to your brain.

Step-by-step explanation:

We have an arythmetical equation that is proposed in the problem.

If the speed of a normal nerve impulse is 100 m per one second, how much will take the same impulse in go throught 2 meters, so it does 2 meters in X s.

`100 m / 1 s = 2 m / x s`

After we have our equation formulated we need to find x

`X s = 2 m * 1 s / 100 m = 0.02 s`

This is the way how we found that there is a time of 0.02 s that takes the nerve impulse to go from the toe to your brain if you are 2 meters tall.
