Answer:
It will take the rocket 43 light years to get to the nearest star
Step-by-step explanation:
1 light year = 9.46 * 10¹⁵ m
speed of light = 3.0 * 10⁸ m/s
In one year, light travels a distance of 1 light year.
A rocket with that travels with a speed 0.1 * the speed of light will travel the distance of one light year in 1/0.1 = 10 light years
Therefore, it will take the rocket 10 * 4.3 light years to get to the star = 43 light years.
43 light years = 43 * 9.46 * 10¹⁴ m = 4.07 * 10¹⁷ m
