Explanation: Radio waves, including radar signals, travel at approximately the speed of light. For radar calculations, it's crucial to remember that the signal travels to the object and back, meaning the elapsed time represents a two-way journey. A common rule of thumb for radar calculations states that it takes approximately 12.36 microseconds for a radio signal to travel one nautical mile and return. This is often called a "radar mile" in terms of time. To find the distance: Distance (nautical miles) = Elapsed time (microseconds) / 12.36 (microseconds per nautical mile round trip) Distance = 62 µs / 12.36 µs/nm Distance ≈ 5.016 nautical miles Therefore, the object is approximately 5 nautical miles away.
