Nerve impulses travel at different speeds. Touch receptors travel at 76.2 m/s, pain receptors travel at 0.610 m/s. I'm 6' 5" tall (1" = 2.540cm) and if I stub my toe. what is the time delay between hittimg my toe and feeling it? What is the time delay between feeling it and feeling the pain?

6' 5" = 77 inches 77/39.4 = 1.96 metres
the time delay between hittig toe and feeling it: t_f = h/v_t h = 1.96 metres v_t - speed of touch receptors t = 1.96/76.2 = 0.026 sec
the time delay between feeling it and feeling the pain: t= t_p - t_f, t_p = h/v_p v_p - speed of pain receptors t = h ( 1/v_p - 1/v_f ) = 1.96 ( 1/0.61 - 1/76.2) = 3.2 sec
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
