Question

If Jim could drive a Jetson’s flying car at a constant speed of 440 km/hr across oceans and space, approximately how long (in millions of years, in 106 years) would he take to drive to a nearby star that is 12.0 light-years away? Use 9.461 × 1012 km/light-year and 8766 hours per year (365.25 days).

    Answer:

    t = 2.94 x 10⁶ years

    Explanation:

    The equation used in the case of constant speed is:

    s = vt

    t = s/v

    where,

    s = distance = 12 light years

    s = (12 light years)(9.461 x 10¹² km/light year) =  113.532 x 10¹² km

    v = speed = 440 km/hr

    t = time passed = ?

    Therefore,

    t = (113.532 x 10¹² km)/(440 km/hr)

    t = 2.58 x 10¹¹ hr

    Now, converting it to years:

    t = (2.58 x 10¹¹ hr)(1 year/8766 hr)

    t = 2.94 x 10⁶ years
