Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
How many km in 4 light years Multip ly by 4?
I would simply multiply them by 4 and if you think there are only 5,800 million million in 1 light year you will have a few trillion in yopur four as if it really matters.

How fast do you need to be to travel 4 light years in one hundred years?
The speed of light is 299,792,458 m/s. distance/speed=time. time=100 years. which is 3153600000 seconds. 4 light years is 299792458*316536000=9454254955488000 meters. So, 9454254955488000/x=3153600000. 9454254955488000/3153600000=2997924.6 m/s. That's 10,792,528.488 km/h. Just to put that in perspective, the fastest speed humans have achieved is about 250,000 km/h (Helios 2 spacecraft.)
