Simple transmission time problem

[SONYFX]

If I have a link that's 1Mbps and 250km long, and I want to transmit 1000bits of info over this link, the speed of signal propagation is 3*10^8. Is the time of transmission calculated as follow?

[(250000)/1Mbps * 1000] + [ 250000 / 3*10^8 ]

calculate overall serialization time (time to clock the 1000 bits) = 1000/1000000 = .001 sec or 1 millisecond.

Then propogation delay. add both together.
