A biophysics student measures her reaction time by having a friend drop a meterstick between her fingers. The meterstick falls 0.32 m before she catches it.

  1. What is her reaction time?

    Reaction time = (s)

  2. Estimate the minimum average speed in cm s−1−1 of nerve impulses going from her eye to her brain and then to her hand assuming the distance from her eye to her brain is 7.8 cm, and the distance from her brain to her hand is 89 cm:

    Speed of impulses = (cm/s)
