Shouldn't there be a question mark after the word "this"?
<<The star nearest to our solar system is said to be 3.8 ly away. How many km away is this? >>
Multiply ten years (converted to seconds) by the speed of light, 3.00*10^5 km/s. That will be the distance in km
For the time required, divide the distance by 100*0.340 km/s = 34 km/s
Actually, spacecraft can go faster than than mach 100. It doesn't make sense to refer to the speed of sound in space
