average distance form earth=384,403,000meters. Multiply by 2π=2,412,743,158meters
orbital period=27days7hours43.1minutes=114,186sec

This gives 2,412,743,158/114,186=21,130meters/sec linear speed.
Wikipedia says 1,021meters/sec

Where's the mistake?

1 day is 86400 seconds, so 27 days can't be 114186 seconds.
