If jim could drive a jetson's flying car at a constant speed of 280 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 8.1 light-years away? use 9.461 × 1012 km/light-year and 8766 hours per year (365.25 days).

It would take approximately 31.2×10^6 years

Explanation:

Average speed = distance/time

Time = distance/average speed

distance = 8.1 light-years = 8.1×9.461×10^12km = 7.66341×10^13km

average speed = 280km/hr = 280km/hr × 8766hrs/year = 2454480km/year

Time = (7.66341×10^13km)/(2454480km/year) = 31.2×10^6 years
