  • Physics - ,

    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.
