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 113 m/s. How much time does it take for the impulse, which travels a distance of 1.50 m, to reach your brain?

d = v * t
1.5 = 113 * t,
t = 1.5 / 113 = 0.01327 s
