A motor neurone carries nerve impulses from the spinal cord to a muscle in the foot.

The length of this motor neurone pathway is 92 cm. Nerve impulses travel along the neurone at a speed of 115 m/s.

Calculate the time it takes for an impulse to travel the full length of this pathway.

Use the equation:

speed=distancetime \text{speed} = \frac{\text{distance}}{\text{time}} speed=timedistance​

Give your answer to 2 significant figures.
