Calculating the time for a packet to go across a link

I found this animation on the web:

https://media.pearsoncmg.com/ph/esm...transmission-propagation-delay-ch1/index.html

I then ran it with the following parameters:

length = 10km
rate = 1 Mps
Packet Size = 100 bytes

The animation specified a propagation speed of 2.8 x 10^8 m/sec
The animation said the time was: 0.850 ms

I attempted to calculate the time by doing the following calculation:
(10e3 / 2.8e8) + (100*8 / 1e6) = 0.0008357 seconds = 0.8357 ms

Where did I go wrong?
