Step 1
1 light-year is approximately equal to 9.461 trillion kilometers. So, 4.4 light-years would be: 4.4 light-years * 9.461 trillion kilometers/light-year = 41.5024 trillion kilometers Show more…

Suppose you wanted to reach Alpha Centauri (4.4 ly from the Solar system) in 100 years. How fast would you have to go, in km/hr? How many times faster is the speed you found in part A than the speeds of our fastest current spacecraft (around 50000 km/hr)?
