it depends on which path its choosing.
there are things called "myelinated" nerve fibres, which are capable of transmitting nerve pulses at the rate of 120m/sec. (our body being hardly 2-3 meters in ht, u can imagine the speed!) these fibers help regulate the posture and maintain the balance of the body.
the touch fibres carry impulses at the rate of 80m/sec
pain fibers transmit at the rate of 15-30m/sec.

Nerve impulses are a combination of electrical signals and chemical reactions. The chemical reactions are by far the slower component.
Nerve impulse velocity varies with the type of impulse. Pressure and position signals travel rapidly (80+ m/s), while pain signals travel orders of magnitude slower (0.6 m/s).
FYI: Electricity, which is the flow of electrons (particles which have mass) cannot move at the speed of light. A mass moving at the speed of light has infinite kinetic energy, which is impossible.

Your question has two meanings
1. Speed of electricity in human body. It is almost the same as every where else i.e. around 3.8 laks km/sec. as human body is a good conductor of electricity.
2.Speed of nerve impulse in human body. This depends on the diameter of the nerve,thicker the nerve faster will be the nerve impulse.The fastest speed in the nerves are 120 mt/sec.

Nuclons depend on spurival tendron impulses which can be
observed through a speclovac meter, giving out the same frequencals as the nerval tentropes emit when exciteloped by
extensial ampelobes, roughly 25 mph.

"Actually, electrons sort of move in a wave like motion seen at a football game in the stands. Each sort of bumps their neighbor in turn. The time it takes for a single electron to migrate this way is much slower than the 11 to 12 inches per nanosecond

The speed of electricity is the speed of light 186,000 miles per second. (that's in a vacuum) It slows a bit with any resistance like flesh, etc but still close

at the rate of 30 to 110 m/s

speed of electricity is the same through any material which is same with speed of light it's plus minus 300000000 meter per second

it depends on how hydrated the body is and the amount of fat or lean body mass
