Solving a problem in physics section 48 point 100 mecha

100. The mixture of lead pellets (density ρ = 11,3 g / cm3) with a diameter of 4 mm and 2 mm at the same time lowered into a vessel of depth h = 1.5 m with glycerol (density ρ ´= 1.26 g / cm3, the dynamic viscosity η = 1,48 Pa • s). Determine how much longer it will take smaller pellets to reach the bottom of the vessel.
