Two concentric circles have radii of $15$ meters and $30$ meters respectively. An antelope starts at point $P$ and runs along a semicircle of the smaller circle, then directly to the outer circle along a radial line, runs along a half circumference of the larger circle, then returns on the same radial path, and completes another semicircle of the smaller circle. Calculate the total distance the antelope travels.
**A)** $45\pi + 30$ meters   
**B)** $60\pi$ meters   
**C)** $60\pi + 30$ meters   
**D)** $75\pi + 30$ meters   
**E)** $90\pi + 40$ meters
