Answer 1

An Earth-sized planet is found to be 9 light years away from the Earth. If you are

travelling in a spaceship with a speed 22 km/s, then how much time will you take to

reach that planet?​

Explanation:

1 Light year = 9.46 X 10¹² Km

Total distance in Km = 9.46 X 10¹² X 9 = 85.14 X 10¹²

Speed of spaceship in Km/s= 22 X 60 X 60 = 79200 Km/s

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

= 1075000000 Hours or 44791666.666667 days or 122716.8949 years
