The distance around the Sun must be 2PI*radius. Change that to meters.
The time to go around is 248 years. Change that to seconds.
speed= distance/time
Check your work here: type into google search window
2*PI*5890E6 km/248years in m/s
Isn't Google calculator magnificent? Now don't depend on this, learn how to do it manually, and use Google calc to CHECK yourself.
