The average time it takes a vesicle to diffuse a distance of x cm is: Time = x^2/2D, where D is the diffusion coefficient. Using this equation, how many hours would it take for a vesicle to diffuse down to the end of a 10cm long axon? You can assume the diffusion coefficient, D=5x10^-8cm^2/s. Also, note that there are 3600 seconds in an hour. (Some notes on format: 2 significant digits is enough. If you wish to use scientific notation, 1.0 x 10^3 should be written as 1.0e3 or 1.0x10^3)
