I think you have misunderstood.
The train from Zurich to Zurich Airport takes about 10 minutes, but only if it is a long distance train. There are local S-Bahn trains as well.
The platforms of Zurich airport rail station are underneath the airport terminal, so there is no horizontal distance as such, just the time taken to do a vertical trip up various escalators into the airport terminal area, the it is just like any other world airport - lots more walking ...
Some trains from places in Switzerland serve the airport direct, so it depends where you travel from
