Answer
23.14 days or $2 \times 10^6 s $.
Work Step by Step
Average velocity of vesicle transport = 1 $ \mu m/s$
Length of axon = 2 m = $2 \times 10^6 \mu m$
Time for travel =?
Velocity = Distance /Time
Time =$Distance / Velocity $
= $2 \times 10^6 \mu m$ /1 $ \mu m/s$
=$2 \times 10^6 s $
Time = $2 \times 10^6 s $
or $ 2 \times 10^6 s / 60s \times60 min \times 24 hrs$
=23.14 days
= $2 \times 10^6 seconds $
