Velocity is the distance traveled divided by the time taken

Velocity is the distance traveled divided by the time taken.
In Carl Sagan's Cosmos Part 8 about 33 minutes in he says,
"We could travel to the Andromeda Galaxy in 28 years ship time."
The Andromeda Galaxy is approximately 2.5 million lightyears away.
2.5e6 lightyears / 28 years = 89,285 light years per year
If a lightyear is a distance and a year is a measure of time,
How is it they are traveling almost 90,000 times the speed of light?
