A neuron is stimulated with an electric pulse. The action potential is detected

Question

A neuron is stimulated with an electric pulse. The action potential is detected at a point 3.30cmdown the axon 0.0050s later. When the action potential is detected 7.10cm from the point of stimulation, the time required is 0.0061s .

Part A

What is the speed of the electric pulse along the axon?

Express your answer to two significant figures and include the appropriate units.

Part B

Why are two measurements needed instead of only one?

Why are two measurements needed instead of only one?

It doesn't matter how many measurements we take, the result will be the same. The action potential is generated instantly and it is very difficult to measure it at once. There may be a time delay from the stimulation of the nerve to the generation of the action potential. None of the above.
