Given:
Jim could drive a Jetson's flying car at a constant speed of 370 km/hr
We will find the time could take to drive to a nearby star that is 12.3 light-years away
Given light year = 9.461 x 10^12 km
And the number of hours per year = 8766 hours
The time = Distance over the speed
so, the time =

Divide the answer by the number of hours per year

So, the answer will be 35.88 Millions of years
