Radio waves are electromagnetic waves used to communicate with satellites in low Earth orbit. Radio waves transmitted from a ground station take 0.0018 s0.0018\text{ s}0.0018 s to reach a satellite. The speed of radio waves is 300 000 000 m/s300\,000\,000\text{ m/s}300000000 m/s. Calculate the distance between the ground station and the satellite. Use the equation: \
