Calculate nerve impulse speed

In a simplified nerve model from a school health-science workshop, an impulse travels \(35\) mm in \(6\) ms. Calculate the speed in mm/ms. Enter the answer and choose the interpretation that best matches the biological evidence.

Worked practice: biological evidence and answer

Use the labelled biological evidence first, then connect it to the final answer.
