Propagation Delay is defined as what?

Propagation delay is the time it takes for a signal to travel from one end of the channel to the other. It depends on how long the channel is and how fast the signal propagates through the medium, so it’s calculated as distance divided by propagation speed. This distinguishes it from other delays, such as the time to push all bits onto the link (transmission delay) or delays created by switching or processing inside equipment. The option that uses only distance ignores how fast the signal moves, and the option that multiplies distance by a constant doesn’t reflect the actual speed relationship. For a practical sense, a longer cable or slower propagation speed increases delay, while a shorter length or faster medium reduces it.
