Hi, Experts please help me with this question

An Earth-sized planet is found to be 9 light-years away from the Earth. If you are
traveling in a spaceship with a speed 22 km/s, then how much time will you take to
reach that planet?​

Dear Student
1 Light year = 9.46 X 10¹² Km(approx)

Total distance  = 9.46 X 10¹² X 9 = 85.14 X 10¹²
(as 9 light year are given
Speed(Km/s)= 22 X 60 X 60 = 79200 Km/s

Approximate Time taken to reach the planet= (85.14 X 10¹²)/ 79200
Regards


= 1075000000 Hours or 44791666.666667 days or 122716.8949 years
