A parsec is an astronomical unit of distance where 1 parsec = 3.26 light years (1 light year equals the distance traveled by light in one year). If the speed of light is 186,000 mi/s, calculate the distance in meters of an object that travels 9.5 parsecs.

    2932016616*10⁸ m

    Explanation:

    1 parsec = 3.26 light years

    Speed of light = 3*10⁸ m/s

    Distance = Speed * Time

    Distance traveled by light in one year

    3*10⁸*365.25*24*60*60

    3.26 light years = 3.26*3*10⁸*365.25*24*60*60 = 308633328 * 10⁸m

    ⇒ 1 parsec = 308633328 * 10⁸m

    9.5 parsecs = 9.5*308633328*10⁸

    ⇒9.5 parsecs = 2932016616*10⁸ m

    Distance in meters of an object that travels 9.5 parsecs is 2932016616*10⁸ m
