Noting that: The propagation speed is 3*10⁸ m/s, the end-to-end data rate from source to destination is 1 Gbps, the processing delay at each satellite is 5s, and the queuing delay at each satellite is 10s (Assume there are no queuing or processing delays at the ground stations), calculate:

The propagation delay

The transmission delay, given that the size of the data is 12.5 Mbytes

The total delay

Which delay(s) you can ignore without affecting the result?
