I averaged over 110km/hr for a kilometer once... ... but that was coming down Mt Tiede in Tenerife on a fairly straight section with a monster tail wind at 8+%
If I were a betting man I'd say you'd got nowhere close to that, even on a world class kilo bike on a track like London or Manchester.
Could be stellar and you could be the next Sir Chris Hoy or it could be very slow and pretty normal for someone just getting started in cycling. There's no way to know as we have no idea how your indoor cycle and it's resistance unit is calibrated. Speed means absolutely nothing indoors other than how fast your wheel is spinning but unless the resistance unit on your indoor bike does a very good job of emulating outdoor, wind and rolling resistance you cannot even begin to compare indoor speed to outdoor speed. As Swampy jests, your indoor bike resistance unit could be emulating a slight downgrade with a tailwind or it could be emulating a steep uphill in which case you should take out your pro license and show those guys how it's done.
Even odds you rode a good ride but nothing equivalent to a minute ten kilo on an actual track.
Well, if you weigh 150lbs and are pedaling on a wooden track at sea level w/ 172.5mm cranks turning at 100 rpm, you're producing about 580 watts......and teams should be searching you out. I think the likely case is that which daveryanwyoming suggested which is that the resistance unit on your indoor trainer isn't calibrated or isn't calibrated well.
