You should mention that sound waves are generated in identical conditions i.e the speed of sound is same in the two experiments.
In that case the ratio is
2v/2L1 : 3v/4L2 = 4L2 : 3L1 .

Physics

α = -π/3 rad/s², θ = 1.5π rad = 0.75 rev

Explanation:

ω₀ = 30 rev/min(2π rad/rev / 60 s/min) = π rad/s

α = (ω₁ - ω₀)/t = (0 - π)/3 = -π/3 rad/s²

θ = (ω₁² - ω₀²) / 2α = (0² - π²) / 2(-π/3) = 3π/2 rad

3π/2 rad / 2π rad/rev = 0.75 rev
