A microwave signal needs $0.24$ seconds to go from a transmitting station on Earth to a satellite and then return to the station on Earth. Microwaves travel at $3.0 \times 10^8\,\text{m s}^{-1}$. What is the distance between the transmitting station and the satellite?
- A$36\,000\ \text{km}$
- B$72\,000\ \text{km}$
- C$36\,000\,000\ \text{km}$
- D$72\,000\,000\ \text{km}$
