Human Nerve Fibers Type A nerve fibers in humans can conduct nerve impulses at speeds up to 140 m/s. (a) How fast are the nerve impulses in miles per hour? (b) How far (in meters) can the impulses travel in 5.0 ms?
The impulses in these nerve axons, which carry commands to the skeletal muscle fibers in the background, travel at speeds of up to 140 m/s.
Speed of the nerve v = 140 m/s
1 h = 3,600 s
The speed of the nerve v in miles/hr is
Speed v = 140 m/s
The distance s = vt
