Asked by Ana
Mrs. Wilson leaves her freshly-baked blueberry pie on the windowsill to cool. The delicious fragrance diffuses through the air with a diffusion coefficient of D = 0.2 cm2/s.
How long does it take for Dennis to smell the pie in his treehouse 10 meters away? Give your answer in days, without entering the unit.
Could you please help me to solve this problem?

I think it's x^2/2D or 1000^2/0.4

t = L^2 / 4D
D = 0.2cm^2 / sec
L = 10 meters or 1000cm
t= 1000^2 / 4 (0.2)
Solve then convert seconds into days.
Hint : The answer is more than 10 days :)
