0.19245 lunar months

Explanation:

T = Orbital time

r = Radius

r_2=\dfrac{1}{3}r_1

1 denotes the moon

2 denotes the satellite

From Kepler's law we have

T^2=\dfrac{4\pi^2r^3}{GM}

So,

\\\Rightarrow T\propto \sqrt{r^3}

\dfrac{T_2}{T_1}=\sqrt{\dfrac{r_2^3}{r_1^3}}\\\Rightarrow \dfrac{T_2}{T_1}=\sqrt{\dfrac{\left(\dfrac{1}{3}r_1\right)^3}{r_1^3}}\\\Rightarrow \dfrac{T_2}{T_1}=0.19245\\\Rightarrow T_2=0.19245T_1

The period of revolution of the satellite is 0.19245 lunar months
