You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 124 m/s. How much time does it take for the impulse, which travels a distance of 1.60 m, to reach your brain?
To calculate the time it takes for the nerve impulse to travel from your foot to your brain, we can use the formula:
Time (t) = Distance (d) / Speed (v)
In this case, the distance is given as 1.60 m and the speed is given as 124 m/s.
Therefore, we can substitute these values into the formula:
t = 1.60 m / 124 m/s
Now let's solve this equation:
t ≈ 0.0129 seconds
So, it takes approximately 0.0129 seconds for the nerve impulse to reach your brain.
