What is the propagation delay on a circuit using a leo satellite orbiting 500 miles above the earth if the speed of the signal is 186,000 miles per second?

Since propagation delay can only be measured in terms of time, we are to determine the time from the given distance and speed. In physics and through dimensional analysis, their relationship is written as:

Speed = Distance/Time
Time = Distance/Speed
Time = 500 miles/(186,000 miles/s)
Time = 2.688×10⁻³ seconds or 2.688 milliseconds

Thus, the propagation delay is 2.688 ms.
