A neuron is stimulated with an electric pulse. The action potential is detected at a point 3.40 cm down the axon 0.0052s later. When the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063s. What is the speed of the electric pulse along the axon? (Why are two measurements needed instead of only one?).
